The molecules in system #2 have a higher kinetic energy because they are at a higher temperature than molecules in system#1.

<h3>Heating of water molecules</h3>

Temperature is defined as a measure of the average kinetic energy of the molecules of a body. The higher the temperature of a body, the higher the kinetic energy of the molecules of the body.

In both systems, we have water molecules that have the same formula H2O. However, the molecules in system #2 have a higher kinetic energy because they are at a higher temperature than molecules in system#1.
