What about the effect of Mr. Heat on the volume in the three states of matter?
Gases expand when heated. For instance, a balloon will pop if it is left in a hot car. It will get smaller if it is put in the refrigerator.
Liquids expand when it's heated, like gas. For example, ice expands when it freezes. As the water molecules lose heat, they vibrate less, and are able to form geometric patterns (A solid has a definite shape and volume) that take up more space. As the volume of ice increases, the density of ice decreases and the ice floats.Density is a measure of mass per volume.
