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

• molecules move away from each other, then around each other
• molecules move in place, then around each other
• molecules move around each other, then away from each other
• molecules move around each other, then in place

If molecules in a substance move in place and energy is transferred into the substance

• then molecules move slower, and it will be a solid
• then molecules will move faster, and it will be a liquid
• then molecules will move faster, and it will be a solid
• then molecules will move slower, and it will be a liquid
