What Happens When Air is Heated?


When we put the aluminum spiral over the hot plate, it spun. I think this is because when air is heated, it rises. So when the hot air rose and touched the top of the aluminum spiral, it came back down it. This is because aluminum is a conductor of heat. So when the heat touched the top of the spiral it had a domino effect and the heat came down the spiral. Simultaneously, another heat wave is coming up to the top of the spiral while heat is going down it. Because there is constant heat going in the same direction, the spiral was spinning. If the heat stopped, it would stop spinning. It is all because heat rises.
