On very warm days, Abby noticed that a metal door fits tightly in its frame and is tough to open. On very cold days, however, Abby noticed the door opens easily. Which choice best explains these differences.

• changing temperatures cause atoms in the metal to become larger or smaller

• cold temperatures cause atoms in the metal to merge together and warm daily temperatures cause atoms in the metal to split apart and become gas

• temperature differences effect the molecular energy of atoms in the metal and they 'slow down' and move closer together or 'speed up' and move farther apart

• the door freezes on cold days and is opens freely on warm days
