As water becomes warmer, boils and then becomes water vapor, what happens to its kinetic and potential energy?

Answer 1

As water becomes warmer and boils, its kinetic energy increases as the particles within the water move faster. When it becomes water vapor, its potential energy also increases, as the particles are able to move more freely and occupy a larger volume. This means that both the kinetic and potential energy of the water increases as it transitions from liquid to gas.
