The objects must be the same temperature and they mus

The objects must be the same temperature and they mus

Answer 1

Conduction requires contact between two objects and a temperature difference.

Step-by-step explanation:

In order for conduction to take place between two objects, they must be in contact with each other. In addition to this, the objects must have a temperature difference. Conduction is the transfer of heat energy between objects through direct molecular collisions.

For example, if you have a hot cup of coffee and you touch a metal spoon to the cup, heat will transfer from the coffee to the spoon through conduction because they are in contact with each other. However, if both objects are at the same temperature, there will be no net transfer of heat.
