Final answer:
Conduction is prevented by different temperatures, as equal temperatures lead to thermal equilibrium.
Step-by-step explanation:
Conduction is the transfer of heat or electricity through a substance. It occurs when there is a temperature difference between two objects or substances in contact with each other. One of the factors that prevents conduction from occurring is different temperatures. For example, if you have a hot object and a cold object in contact, heat will flow from the hot object to the cold object until they reach the same temperature, and conduction will stop. On the other hand, equal temperatures do not prevent conduction, as the objects or substances will already be in thermal equilibrium and heat will not flow.
