Question

Heat is the energy transferred between two bodies in contact due to the difference in their ______________.

Answer 1

1. Heat flows when there is a temperature difference between two bodies that are in contact with each other.
2. The flow continues until both the body attains the same temperature.
3. When both the body attains the same temperature then the body is said to be in thermal equilibrium.

Hence, heat is the energy transferred between two bodies in contact due to the difference in their temperature.
