Answer 2

The objects must be different temperatures and they must be in contact.

Step-by-step 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.
