You find a substance in your water bottle. The molecules in the bottle are moving around each other. You increase the speed of the molecules and cause a phase change. How did you do this and how did this affect the substance? You transferred energy....

• into the substance and it changed to a gas

• into the substance and it changed to a liquid

• out of the substance and it changed to a solid

• out of the substance and it changed to a liquid
