Ice To Water Vapor. Ice to water then to vapor under sunlight. This is not a video for.
However pure water never acts as a conductor.
Water to water vapour by the process of evaporation/vaporization. There are three heats to consider #q_3# = heat required to vapourize the water to vapour at 100 °c. The enthalpy change as ice changes to water and vapor is one of the most common enthalpy problems. Because the saturation vapor pressure over water is greater than that over ice, the dew point for a given water vapor content is always less than the frost point.
