Question

I have a room that is sealed air tight that is sitting at 90 degrees and another room, also sealed air tight, that is sitting at 40 degrees. What happens when I open the door between the rooms? How does the air flow? What does the temperature become when the rooms reach equilibrium?

Answer 1

Answer: When you open the door between the two rooms, the air will flow from the warmer room to the cooler room until the temperatures in both rooms reach equilibrium. This process is called heat transfer. The final temperature will depend on the size and insulation of the rooms, as well as other factors such as humidity and air pressure.
