Will the kinetic and potential energies of water molecules change in a tightly sealed jar of cold water

Will the kinetic and potential energies of water molecules change in a tightly sealed jar of cold water if it is immersed in hot water?

Only kinetic energy will increase.
As a result of the difference in temperatures in the can with cold water and hot water, heat exchange will begin, as a result of which the can with cold water heats up. All moving particles in a can of cold water will have an increase in kinetic energy and interaction energy. Since the average distance between water molecules remains constant and independent of temperature, the potential energy will remain unchanged.
