Heat is transferred from hot objects to cold objects .
For Example -
- A pan becomes hot when kept on the flame - Heat transferred from flame to pan
- It cools down again when the flame is switched off - Heat transferred from pan to surroundings
- The other end of a rod would heat if a flame is applied to one end - Transfer of heat through the rod from the hotter end to the colder end.
- This implies that heat cannot be transferred if two objects have the same temperature .
