Answer 1

If a copper rod at 50°C is dropped in a jar containing water at 50°C, the heat will not flow.

Explanation:

Heat energy only transfers between objects when there is a difference in temperature. Since both the copper rod and the water are at the same temperature (50°C), they are in thermal equilibrium.
