In Class today we went to the Phet website. Then go to play with sims, Then go to states of matter. First he wanted to see what would happen if we put an icecube on a counter. We councluded that if you do the particles would start to heat up and vibrate faster. The next question was what would happen to the motion of the particles if it changed from solid to liquid. Also if it changed from liquid to gas. We said that the particles were vibrateing and spreading out.
