2. After putting ice on top of the glass and submerging the glass at the bottom in hot water, were you able to easily separate the glasses? What do you think to happen on the molecules of these glasses?
Fill the top glass with ice water; the cold will make the glass molecules contract. With the top glass still full of ice water, run hot water over the bottom glass, or place it in a few inches of hot water. The heat makes the bottom glass expand. Gently twist the two glasses; they should come apart easily.
