Answer:
The objects must be different temperatures and they must be in contact.
Explanation:
For conduction to take place between two objects, they must be in contact with one another and at different temperatures.
- Generally, heat transfer takes place over a gradient i.e. from a region of higher temperature to one with a low temperature.
- If two places or bodies have the same temperature, heat transfer will not take place.
- In conduction, the two bodies must be in contact with one another.
- The collision of molecules of one body transfers this kinetic energy to the other one in contact with it.
