What is true about kinetic energy?
Responses-
a- Molecules within a substance have kinetic energy when that substance moves.
b- Cold molecules have potential energy but no kinetic energy, as kinetic energy is experienced as heat.
c- Molecules of liquids and gases are in constant motion, so they have kinetic energy.
d- All molecules are in constant motion, so they all have some kinetic energy.
