Heat is flowing from the living room to the bedroom. I need to draw a diagram that shows what you know about the temperature in each room...what should I do?
Heat can flow if warm air is interacting with cooler air. (lesser and greater densities) It always seeks equalibrium. In that state all the molecules of air have the same average velocity. Your diagram could use red for warmer air and blue for cooler air. With arrows of blue and red flowing towards one another.
Some pictures at the following link may help:

Use the NEXT BUTTON when there.
