Question
Heat travels from _________ to cold body.
- Hot body
- Cold body
- Normal body
- None of the above
Hint:
The atoms in the hot bodies have higher kinetic energy than those of the cold bodies.
The correct answer is: Hot body
- Thus to maintain thermal equilibrium, the atoms of higher kinetic energy tries to move and collide with the atoms of low kinetic energy.
- Thus heat transfers from a hot body to a cold body.
