Question
The direction of heat flow is from _________ to low.
- Low
- Zero
- High
- Deep
Hint:
- The direction of flow of heat between two bodies is determined by their temperatures .
The correct answer is: High
- The direction of flow of heat between two bodies is determined by their temperatures .
- The atoms in the hot bodies have higher kinetic energy than those of the cold bodies. 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.
- Hence Heat flows from High to Low
