What happens when ice transform into steam

The thermal kinetic energy of the molecules is raised

Explanation:

As it takes some amount of heat energy to be converted to thermal energy to turn ice into water and water into a stream. As this state change, the temperature will rise again.  As the energy generated is being measured in Joule, a more commonly studied unit is a calorie. As matter vary in their capacity to absorb heat. Like ice needs about  0.50 as specific heat, water as 1.00 and stream 0.48 cal/g in degrees C. As the matter is heated the latent or hidden energy is released and tends to remain until the material changes its state.
