Ice Cube?
Of course heat is added because you are turning solid which is like ice to gas which is water vapour !!
vapour
The antonym for vapor is solid.
As the word "vapour" indicates, it is a gas.
It's called condensation when vapour cools and turns into liquid.
Frost is water vapour, or water in gas form that when freezes, becomes a solid. Frost forms when the outside temperature cools past the dew point. The dew point is the point where the dew gets so cold, the water vapour in the atmosphere turns into liquid and if cold enough the liquid freezes
As the word "vapour" indicates, it is a gas.
It condenses and turns into vapour which is known as "steam".
Condensation.
vapour
Dry ice (solid CO2) sublimes- the cold CO2 - the "fog" is caused by condensation of water vapour in the air. Another example is solid iodine, which when heated in a test tube sublimes and precipiattes at the cool end of the tube.
Water turns to solid when it freezes.
