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.
