Which of the following options is correct when two objects at the same temperature are kept in contact with each other?
No heat is transferred.
When two objects are at the same temperature and are kept in contact with each other, no heat is transferred between them. This is because heat
transfer occurs due to a temperature difference between objects. According to the zeroth law of thermodynamics, thermal equilibrium is achieved when two objects reach the same temperature, meaning there is no net flow of thermal energy. Hence, the correct option is:
No heat is transferred.
