What is it called when the particles in matter gain or lose enough energy that they change from one state of matter to another?
a) chemical change
b) chemical reaction
c) physical change

Which state of matter would a substance be if the particles in it had enough energy to prevent bonding, but not enough energy move freely, allowing them to flow, but have a constant volume?
a) solid
b) liquid
c) gas
d) plasma
