Chapter 5, Problem 35R

To determine

To state: The form of energy that is transferred between the objects due to a temperature difference between them.

Explanation of Solution

Introduction:

Temperature is the degree measure of hotness or coldness of a body and in fact, it is the term which is the measure of the average kinetic energy of particles of the body.

There is always a transfer of heat from a body at a higher temperature to a body at a lower temperature, i.e., from a hotter body to a cooler body. Heat is a form of energy that transfers from a hotter region towards a cooler region due to a difference in temperature in them and it takes place by three different methods: conduction, convection and radiation. In conduction, there is heat transfer from a hotter part to a cooler part due to the collision of molecules. In convection, heat transfers due to the rising of warmer fluid and cooler fluid rush to take its place while in radiation, the transfer of energy takes place in the form of waves through space.

Conclusion:

Hence, the energy that is transferred between objects due to the temperature difference between them is heat.
