Outdoor weather: hoarfrost
Physically: sublimation
When the water gets supper hot it can change to water vapor.
The phase change is called deposition: water vapor changes directly to ice.
Water vapor usually condenses into a liquid state (water); but, if the conditions are cold enough it can condense straight into a sold form (ice or frost), just like when frost appears on railings or windows after a cold night.
When water changes to water vapor, it has changed its state from liquid to vapor and no chemical change has taken place. It's only a physical change.
No, this is definitely a physical change, absolutely not a chemical.
Frost is a physical change, the condensation and freezing of water vapor.
When water vapor meets a surface that is below the freezing temperature and below the dew point, it turns into frost.
Air frost - or ground frost
When water vapor condenses on particles in the air, the water molecules liquefy and become liquid water.
Rime frost is freezing water vapor that condenses at ground level.

This is an example of a change in the physical states of Matter. These states-of-Matter are: Solid, Liquid, Gas and the Newest and Latest and most energetic State - Plasma. Frost is a special 'case' because it does not Condense [vapor to liquid], it Sublimes - water [in this case] vapor crystallizing [directly] to the Solid - bypassing the liquid phase.
The change from water vapor to liquid water is called condensation.
What forms is frost.
