Question

How are the molecules of the state of matter related to heat energy? Please don't answer irrelevant answers or i may have to report you... Thanks!

Answer 1

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.
