Question

Conduction can only occur between two objects when – both objects are exactly the same temperature. Both objects are exactly the same temperature. One of the objects is made of a metal. One of the objects is made of a metal. Both objects are in physical contact with each other. Both objects are in physical contact with each other. One object is less dense than the other. One object is less dense than the other.

Answer 1

Both objects are in physical contact with each other

Step-by-step explanation:

Conduction refers to the flow of heat from one object to another when the both objects are in contact with each other.

Hence, before heat can flow from one object to another, the two objects must be in contact with each other. This is a key requirement before conduction can take place.
