Question

Will heat transfer take place if objects in contact are at the same temperature? Q6.

Answer 1

Answer:

No, the transfer of heat will not take place if the objects in contact are at the same temp.

If two objects at different temperatures are brought in contact with each other, energy is transferred from the hotter object (that is, the object with the greater temperature) to the colder (lower temperature) object, until both objects are at the same temperature.

The zeroth law says when two objects at thermal equilibrium are in contact, there is no net heat transfer between the objects; therefore, they are the same temperature.
