Did the argon change state as you heated the atoms?

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. Solids, liquids and gases all expand when heat is added. When heat leaves all substances, the molecules vibrate slower. So yes, it can if the heat is strong enough to change the objects compesistion! :)
