How can a glass of water and a river have the same temperature but different amounts of thermal energy?

Note that temperature and thermal energy are different from each other. Temperature is an average and thermal energy is a total. A glass of water can have the same temperature as Lake Superior, but the lake has far more thermal energy because the lake contains many more water molecules.

When two objects of different materials have the same temperature do they have the same amount of heat?

The zeroth law of thermodynamics defines thermal equilibrium within an isolated system. The zeroth law says when two objects at thermal equilibrium are in contact, there is no net heat transfer between the objects; therefore, they are the same temperature.

When two objects with different temperatures are put in contact with each other they both achieve the same temperature after sometime Why is it so?

The objects will exchange thermal energy until their temperatures are equal. Two objects at different temperatures when placed in contact will eventually come to the same temperature. It happens due to thermal equilibrium.

Do you think two bodies have same heat if they are in same temperature give example to support to your answer?

No specific heat is different for different material. The masses of the two bodies are same but as there is a difference in temperature it means there is a definite difference in their specific heat. Heat energy depends on the mass, specific heat capacity and change in temp.

Why the heat content in two bodies may differ even though the temperature remains same?

As the temperature of the two bodies are same they are in thermal equilibrium which means there would be no transfer of heat energy between them. Flow of heat energy takes place when there is temperature difference between the bodies which are in contact with each other.

How mechanical energy and thermal energy can be different if they have the same components?

Mechanical energy is the ordered movement of the molecules as a single unit. Thermal energy is the random movement of the molecules. Mechanical energy can be 100% converted to thermal energy, but thermal energy cannot be fully converted to mechanical energy.

What happens when two bodies of matter at different temperatures are brought together?

If two bodies at different temperatures are brought together, energy is transferred—i.e., heat flows—from the hotter body to the colder. The effect of this transfer of energy usually, but not always, is an increase in the temperature of the colder body and a decrease in the temperature of the hotter body.

How would a spoon get hot when it is in a cup of hot water?

In this experiment when we placed the spoons in the boiling water, the fast-moving water particles collide with the slow-moving spoon particles. As a result of the collision between the water particles and spoon particles, the particles of the spoon begin to move faster and the metal spoon becomes hotter.

How are temperature and mass related to thermal energy?

Thermal Energy, Temperature, and Mass

Both reflect the kinetic energy of moving particles of matter. However, temperature is the average kinetic energy of particles of matter, whereas thermal energy is the total kinetic energy of particles of matter.

How does heat flow between two objects of different temperatures?

Heat flow. When you bring two objects of different temperature together, energy will always be transferred from the hotter to the cooler object. The objects will exchange thermal energy, until thermal equilibrium is reached, i.e. until their temperatures are equal.

When two objects reach the same temperature after some time in contact with each other?

When two objects in contact with each other are at different temperatures, they are said to be in thermal equilibrium. When two objects in contact with each other are at the same temperature, they are said to be in thermal equilibrium.

Can two objects of the same mass but different composition have the same total internal energy of their temperatures are not the same?

Yes. Internal energy = potential energy + ke of particles. If one substance has a different potential energy, adjusting the KE of the particles can make the total ( the internal energy) the same.

When two objects of different temperatures are placed in contact the temperature of the warmer object decreases and the temperature of the cooler object increases?

Heat Transfer: The movement of heat from a warmer object to a colder one – when two substances at different temperatures are mixed together, heat flows from the warmer body to the cooler body until they reach the same temperature (Zeroth Law of Thermodynamics – Thermal Equilibrium).

Why do objects with the same temperature have the same internal energy?

Internal energy is about all forms of energy (kinetic + interactions energies) in the system and temperature is only about kinetic energy. So, same temperature don’t means.

Do you think two bodies have same heat if they are in same temperature?

No, They may have different heat. Explanation: It is because there is a concept of latent heat of fusion and latent heat of vaporization.

What is mechanical energy How does it differ from thermal energy what are the forms of mechanical energy of a fluid stream?

It differs from thermal energy in that thermal energy cannot be converted to work directly and completely. The forms of mechanical energy of a fluid stream are kinetic, potential, and flow energies.

Are heat and thermal energy the same?

Thermal energy refers to the energy contained within a system that is responsible for its temperature. Heat is the flow of thermal energy.

What happens to the water inside the glass after pouring hot water in it?

Once you pour boiling water into the glass, the inside part of the glass expands due to heat while the outer layer remains cool. The temperature difference will cause the inner layer to expand far greater than the outer part.

How are heat internal energy and thermal energy related to each other?

Thermal and internal energy is equal to the sum total kinetic energy possessed by the the molecules whereas the heat energy is the transfer of thermal energy from high temperature to low temperature.

How does the sun’s heat travel to Earth?

The Sun’s energy gets to the Earth through radiation, which you can prove just by standing outside and letting the sun’s rays warm your face on a sunny day. Every object around you is continually radiating, unless its temperature is at absolute zero, at which point its molecules completely stop moving.

What happens to the molecules in the water as it remains in contact with the spoon?

The faster-moving atoms in the spoon transfer some of their energy to the water molecules. This causes the water molecules to move a little faster and the temperature of the water to increase.

How are thermal energy and temperature similar and different?

Temperature measures the average kinetic energy of the particles in a substance. Thermal energy measures the total kinetic energy of the particles in a substance. The greater the motion of particles, the higher a substance’s temperature and thermal energy.

Does temperature depend on mass?

Temperature is an intensive quantity that does not depend on the mass of material that you have.

How does mass affect the temperature?

To double the temperature change of a mass m, you need to add twice the heat. (b) The amount of heat transferred is also directly proportional to the mass. To cause an equivalent temperature change in a doubled mass, you need to add twice the heat.

How is something different when it is warmer or cooler?

Introduction. (The first law of thermodynamics) When you put a hot object in contact with a cold one, heat will flow from the warmer to the cooler. As a result, the warmer one will usually cool down and the cooler one will usually warm up. Eventually, they will reach the same temperature and heat flow will stop.

When heat flows from a warmer object in contact with a colder object do the two have the same temperature changes?

When two objects have different temperatures, heat is transferred. The cooler object gets warmer until the two objects have the same temperature. Heat energy always flows from the warmer object to the cooler object.

Is it possible for two objects to be in thermal equilibrium if they are not in contact with each other explain?

Two objects are in thermal equilibrium if they are in close contact that allows either to gain energy from the other, but nevertheless, no net energy is transferred between them. Even when not in contact, they are in thermal equilibrium if, when they are placed in contact, no net energy is transferred between them.

What would happen if the temperature of two objects are same?

As we have seen in the zeroth law of thermodynamics, when two objects are placed in contact heat (energy) is transferred from one to the other until they reach the same temperature (are in thermal equilibrium). When the objects are at the same temperature there is no heat transfer.

What happens when two things are the same temperature?

When two objects are in thermal equilibrium they are said to have the same temperature. During the process of reaching thermal equilibrium, heat, which is a form of energy, is transferred between the objects.

Can two objects of different masses and different materials have the same heat capacity?

No, different materials have different specific heat capacities so the body with the lower specific heat will have the higher final temperature.

Can two objects have the same temperature and the same thermal energy quizlet?

Thermal energy, however, does depend on the amount. So if one object has few molecules with a high temperature, it may have the same thermal energy as another object that has many molecules at a lower temperature. An example might be a lit match and an ice sculpture. You just studied 19 terms!

Why do different objects have different specific heat capacities?

The specific heats and molar heat capacities of different substances can be quite different; they reflect both molecular structure and intermolecular interactions (for solids and liquids, but not gases).

When two objects with different temperatures are put in contact with each other they both achieve the same temperature after sometime Why is it so?

The objects will exchange thermal energy until their temperatures are equal. Two objects at different temperatures when placed in contact will eventually come to the same temperature. It happens due to thermal equilibrium.

How are thermal and mechanical energy different?

Mechanical energy is the ordered movement of the molecules as a single unit. Thermal energy is the random movement of the molecules. Mechanical energy can be 100% converted to thermal energy, but thermal energy cannot be fully converted to mechanical energy.

How does it differ from thermal energy?

Heat energy is a form of energy that is in transit, whereas thermal energy refers to the total energy of all the particles contained within a system and maintained at a specific temperature.

How is mechanical energy different from hydraulic energy?

Answer: 1) Hydroelectric power is a renewable energy source which harnesses the power of moving water to produce electricity. … A hydroelectric dam converts the potential energy stored in a water reservoir behind a dam to mechanical energy—mechanical energy is also known as kinetic energy.

What is the difference between temperature thermal energy and heat quizlet?

What is the difference between heat and temperature? Temperature is the average energy of the matter, heat is the transfer of thermal energy from one place to another. Thermal energy measures the total energy of moving particles.

How does heat differ from thermal energy under what condition is heat transferred from one system to another?

If there is a temperature difference between two systems heat will always find a way to transfer from the higher to lower system. Conduction is the transfer of heat between substances that are in direct contact with each other. The better the conductor, the more rapidly heat will be transferred.

How are heat thermal energy and temperature related?

When the temperature of an object increases, the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object’s thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.

How does heat differ from internal energy or are they two terms for the same thing?

How does heat differ from internal energy, or are they two terms for the same thing? Internal energy is a total of all energy in a substance. Heat is the internal energy transferred from a hot object to a cold object. They are NOT the same thing.

How is heat lost in space?

“In space there is no air for conduction or convection,” he added. Space is a radiation-dominated environment. Objects heat up by absorbing sunlight and they cool off by emitting infrared energy, a form of radiation which is invisible to the human eye.

Can you feel heat in space?

Since there is no way to conduct heat, the temperature of the objects in the space will remain the same for a long time. Hot objects stay hot and cold things stay cold. But, when the sun’s radiations enter the earth’s atmosphere, there is a lot of matter to energize. Hence, we feel the radiation of the sun as heat.

In what direction will heat flow between two objects with different temperatures?

When you bring two objects of different temperature together, energy will always be transferred from the hotter to the cooler object. The objects will exchange thermal energy, until thermal equilibrium is reached, i.e. until their temperatures are equal. We say that heat flows from the hotter to the cooler object.

Is it OK to put boiling water in a glass?

The effect of thermal shock is powerful and results in the cracking of glass. Even heat-resistant glasses like Pyrex can shatter when poured with boiling water incorrectly. To prevent the glass from cracking when exposed to boiling water, you should avoid extreme and abrupt changes in temperature.

Can you put boiling water in a candle jar?

Use Boiling Water

Pour boiling water into the container, leaving room at the top. (If your candle is made of a soft wax, such as soy wax, you can use hot water that’s not boiling.) The boiling water will melt the wax and it will float to the top. Let the water cool and remove the wax.
