When the sun’s radiant energy falls on earth’s oceans, it causes water to change state by evaporating. which form of energy does water vapor have?

The correct answer is chemical potential energy.

Explanation:

When the radiation energy of the Sun falls on the surface of the oceans, it makes the water to modify its state by undergoing evaporation. The form of energy exhibited by the water vapor is chemical potential energy.  

When the energy from the Sun falls on the surface of the water, a change in the state takes place, that is, from liquid to gas. This gas elevates above in the form of water vapor, and this is a chemical change. This vapor possesses the tendency to get transformed into other forms. Thus, the energy present within the water vapor is known as chemical potential energy.
