Why does temperature increase between changes of physical state?
Alekssandra [29.7K]
As temperatures increase, additional heat energy is applied to the constituent parts of a solid, which causes additional molecular motion. Molecules begin to push against one another and overall volume of a substance increases. When thermal energy is added to a substance, it’s temperature increases.
