* Thermal energy: This is the most obvious form of energy in hot steam. The water molecules in steam are moving rapidly due to their high temperature, and this kinetic energy is what we perceive as heat.

* Potential energy: Steam molecules have potential energy due to the forces of attraction between them. The further apart the molecules are (like in a gas), the more potential energy they possess.

* Latent heat of vaporization: This is the energy that was required to transform the water from a liquid to a gas. This energy is stored within the steam molecules and can be released as the steam condenses back into liquid water.

In summary: Hot steam contains thermal energy, potential energy, and latent heat of vaporization. The specific proportions of these energies will depend on the temperature and pressure of the steam.
