When the door opens between the two rooms, heat will transfer from the warmer room to the colder room. As a result, the temperature in the warmer room will decrease, and the temperature in the colder room will increase. Therefore, the statement "The temperature in both rooms will become equal over time" is the best description of what will happen as the door opens between the two rooms.
