... kinetic theory deals with atoms vibrating as they receive more energy and they then break their bonds. This is linked to this experiment as the squash ball's atoms get more energy and vibrate more before breaking their bonds to become a liquid when the ball hits a critical temperature. I don't think the graph will go through 0,0, as even when the ball is at 0 degrees it will still bounce. I am using a large range of results as well. Method We set up the apparatus as shown in diagram and then heated the ball to a set temperature. We then dropped it from 70 cm high and measured the bounce. We then repeated that temperature another 4 times to gain an average. We had to be careful with the Bunsen burner and so we wore goggles. To keep the experiment fair the only thing, which we changed each time, was ...
