Miller is standing in the doorway between a warm room and a cold room. Can you see which room is the warmest? Look at the flame. Which way is it turning ? A wind is created at the top of the doorway when the warm air enters the cold room and rises. Click Miller |
The wind continues to blow, as long as there is a difference in temperature between the two rooms. The fire in the fireplace heats the air. Click Miller |

At the bottom the wind is going the other way from the cold to the warm room. Warm air is light and rises. Click Miller |
