What must be true about two objects for conduction to take place? The objects must be different temperatures and they must be in contact.
The objects must be the same temperature and they must be in contact
The objects must be different temperatures and they must be insulators.
O The objects must be the same temperature and they must be insulators.

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.
