What happens to a substance when it is heated? a
Thermal energy is decreased
b
Potential energy is increased
c
Kinetic energy is increased
d
It does not change its physical shape

C

Explanation:

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.
