If you have a liquid that changes to a gas, explain it's freedom of movement in both phases

• Molecules move around each other, then in place

• Molecules move around each other, then away from each other

• Molecules move away from each other, then in place

• Molecules move in place, then move around each other

Before: Molecules move around each other

After: Molecules move in place

• The substance was a liquid and changed into a solid

• The substance was a liquid and changed into a gas

• The substance was a gas and changed into a liquid

• The substance was a solid before and after
