check_circleExpert Solution
Step 1

Heat: Heat is a form of energy that is transferred from one body to another because of difference in temperature. When a body at a higher temperature is placed in contact with a body at a lower temperature, heat transfer takes place from the one at higher temperature to the one at lower temperature.

The units of heat is same as energy (cal/ Joules).

Step 2

Difference between heat and thermal energy:

Thermal energy is defined as the energy possessed by a body at a particular temperature due to the motion of the molecules. It is a fo...
