What causes different specific heats?

This quantity is known as the specific heat capacity (or simply, the specific heat), which is the heat capacity per unit mass of a material. Experiments show that the transferred heat depends on three factors: (1) The change in temperature, (2) the mass of the system, and (3) the substance and phase of the substance.

How are heat and temperature related but different?

The core difference is that heat deals with thermal energy, whereas temperature is more concerned with molecular kinetic energy. Heat is the transfer of thermal energy, whereas temperature is a property the object exhibits.

Can heat flow with same temperature?

Heat is that form of energy which is transferred due to a temperature difference. No. Temperature is the correct variable, not heat content. Now, heat will flow between the two bodies – the question is whether there is net heat flow.

Is it possible for two items that are touching to have the same temperature but not the same amount of thermal energy?

Identical masses of different materials can have different amounts of thermal energy, even at the same temperature. This means that the material that makes up the substance is a third factor that affects how much thermal energy a substance has.

What happens when two things have 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.

How does the heat flow of materials having different temperatures?

Heat will flow from the high temperature region to the low temperature region until the temperature distribution is the same throughtout the body. Or, there may be a temperature gradient across an object. Heat will flow so as to equalize the temperature throughout the object.

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?

Answer: If two objects at different temperatures are brought in contact with each other, energy is transferred from the hotter to the colder object until equilibrium is reached and the bodies reach thermal equilibrium (i.e., they are at the same temperature).

How do different materials 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).

Why do different substances heat up at different rates?

A material’s specific heat capacity has to do with many factors, but one of the most important is the mass of its individual atoms or molecules. It turns out that materials with lighter atoms tend to have higher specific heat capacities (take more energy to heat up) than materials with heavier atoms.

Is specific heat a different constant for each material?

Specific heat capacity often varies with temperature, and is different for each state of matter. Liquid water has one of the highest specific heat capacities among common substances, about 4184 J⋅kg⁻¹⋅K⁻¹ at 20 °C; but that of ice, just below 0 °C, is only 2093 J⋅kg⁻¹⋅K⁻¹.

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).

When two objects come in contact heating continues until both objects have the same?

It is the temperature difference between the two neighboring objects that causes this heat transfer. The heat transfer continues until the two objects have reached thermal equilibrium and are at the same temperature.

Can an object be hotter than another if they are at same temperature?

An object is hotter than another if they are at same temperature but if the temperature of one object is higher than that of the other object, there will be transfer of energy from the hotter to the colder object until both objects reach the same temperature.

When two molecules of unequal temperature make contact heat pass from the warmer to the cooler molecule until they are the same temperature?

Conduction occurs when two substances at different temperatures are in contact. Energy is always transferred from the substance with the higher temperature to the one at lower temperature.

Can two objects have the same temperature but different amount of heat energy?

Note that heat capacity is the same as specific heat, but without any dependence on mass. Consequently, two objects made up of the same material but with different masses will have different heat capacities.

Do two substances at different temperatures achieve thermal equilibrium if they have equal changes in temperature?

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.

Why do some materials feel hotter than others even if the two materials are at the same temperature?

In general, metals feel colder or hotter to the touch than other materials at the same temperature because they’re good thermal conductors. This means they easily transfer heat to colder objects or absorb heat from warmer objects.

Can two different materials have the same value of specific heat capacity?

It should be noted that two substances can have the same specific heat capacity just as two substances can have the same density, but for example, if the heat capacity of a clear liquid is not 1 cal/g^oC, the substance can not be pure water.

What systems keep something inside them the same temperature either hot or cold without using electricity?

The answer is thermal insulation. Insulation means creating a barrier between the hot and the cold object that reduces heat transfer by either reflecting thermal radiation or decreasing thermal conduction and convection from one object to the other.

Why do different materials feel different?

Although things made up of different materials are preserved under same temperature conditions in the same room, they may feel relatively warmer or colder than the other materials. This can be explained by the effect of a material-specific parameter called Thermal conductivity.

Which factors affect heat transfer between a warm and a cool substance?

Which factors affect heat transfer between a warm and a cool substance? chemical composition of the substances. state of matter of the substances at room temperature. thermal equilibrium of the substances.

Will a swimming pool or bathtub heat up faster?

Assuming they both start at the same temperature, which will heat up faster, a swimming pool or a bath tub? Explain your thinking. Bath tub. The Swimming pool has more mass.

Why does steel have different specific heat?

Each different type of metal causes the temperature of the water to increase to a different final temperature. This indicates that each metal has a different ability to absorb heat energy and to transfer heat energy. The ability of a substance to contain or absorb heat energy is called its heat capacity.

How do we decide which object is hotter than the other?

A reliable measure of the hotness of an object is its temperature. Temperature is measured by a device called thermometer.

Which of the object is hotter which has a lower temperature?

The macroscopic feature of objects with a higher heat is a higher temperature . Hotter objects have a higher average kinetic energy and a higher temperature; cooler objects have a lower average kinetic energy and a lower temperature.

Are thermometry and calorimetry same?

Why different object kept on a table at room temperature do not exchange heat with the table?

1 Answer. The objects do exchange heat with the table but there is no net transfer of energy (heat) as the objects and the table are at the same temperature.

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

this state is known as thermal equilibrium. 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.

What happens when two things have 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.

Why does heat move from warmer to colder objects?

Heat is always the transfer of energy from an object at a higher temperature to an object at a lower temperature. So energy flows from the particles in the warmer bowl to the particles in the cold ice and, later, the cooler water.

When two systems that have the same temperature are put in contact with each other is there heat transfer going on?

When the two systems are in contact, heat will be transferred through molecular collisions from the hotter system to the cooler system. The thermal energy will flow in that direction until the two objects are at the same temperature.

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

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. Explanation: Temperature is a measure of the average kinetic energy of the atoms or molecules in the system.

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.

What do you know about heat and temperature How would you compare heat and temperature?

The core difference is that heat deals with thermal energy, whereas temperature is more concerned with molecular kinetic energy. Heat is the transfer of thermal energy, whereas temperature is a property the object exhibits.

Why does metal feel colder than wood even when they are both at the same temperature?

This observation is usually attributed to metals having higher thermal conductivity than wood. They extract more heat from your hand than wood in a given time. Therefore, you perceive the metal as being colder than the wood.

How does temperature difference relate to the rate of heat transfer?

The rate at which temperature changes is proportional to the rate at which heat is transferred. The temperature of a sample changes more rapidly if heat is transferred at a high rate and less rapidly if heat is transferred at a low rate.

Why do metals feel both colder in the winter and hotter in the summer?

Metal is dense and because of both the density and structure of metals, they are efficient at heat transfer and energy transfer, like electricity. The second law of thermodynamics says that heat always flows from a warmer object to a cooler one.

How are the cup features that keep things cold the same or different for keeping things hot?

The air between the two walls is sucked out during construction, creating a vacuum. Instead of containing some kind of heating element to keep hot things hot, a thermos is designed to keep hot things hot by not allowing heat to escape. Heat can be transferred through the air.

How do insulators keep things warm?

Insulation helps keep cold things from warming up and warm things from cooling down. Insulators do this by slowing down the loss of heat from warm things and the gaining of heat by cool things. Plastics and rubber are usually good insulators.

What is the relationship of temperature to heat?

Explanation: heat is the total energy of the motion of the molecules inside the object or particle, whereas Temperature is merely a measure of this energy. The relationship could be, the more heated an object is there higher the temperature the object will have.

Can Different materials have different temperatures?

If you leave metal and wood in contact, without major energy flow to or from other things, they’ll come to the same temperature. That’s true for any materials. However, they won’t feel like the same temperature, because the metal has higher thermal conductivity.

Why do things feel different temperatures?

Some objects feel colder than others. Why? The temperature of an object is dependant on its heat capacity and the rate at which heat can be removed from its surface. The energy required to heat up a certain volume of material differs.

How does temperature affect specific heat capacity?

Many properties of substances vary with temperature; so does heat capacity. On a deeper level, as you rise the temperature, more and more degrees of freedom unfreeze, so the heat capacity grows. (Water vs vapor is a notable exception.) At zero K, heat capacity of anything tends to 0.

Why do different materials heat up at different rates?

A material’s specific heat capacity has to do with many factors, but one of the most important is the mass of its individual atoms or molecules. It turns out that materials with lighter atoms tend to have higher specific heat capacities (take more energy to heat up) than materials with heavier atoms.
