• gas
• plasma

Sam had a solid and added energy to it. What did the molecules look like?

• The molecules moved in place.
• The molecules moved away from each other.
• The molecules didn't move.
• The molecules moved around each other.

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

Before: molecules move around each other, After: molecules move in place

• Before, the substance was a solid and later a liquid.
• Before,the substance was a gas, and later a liquid.
• Before, the substance was a liquid and later a solid.
• Before,the substance was a liquid, and later a gas.
