Answer:
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. ... When heat leaves all substances, the molecules vibrate slower.
The absorption of energy impact on the speed of the particles should be explained below.
In the case when the heat should be added to the substance so here the molecules and the atoms should be vibrate faster. Since the vibration of the atom should be faster so the space that arise between atoms should be increased. It measures the state of matter of the substance. However, when the heat left all kind of substance so the molecule vibrate the slower.
