Before a gas can freeze it must first condense and become a liquid. Then the liquefied gas can freeze if the temperature or pressure is reduced enough. The change that take place is that the molecules move much slower and interact with each other more often, producing the physical characteristics of a solid.
To turn a liquid into a solid you have to freeze it. To turn a gas into a solid you must first turn it into a liquid, then freeze it.
i am a scientist. variation dose take place when a solid is turned to a gas.
It be evaporation. ~answered by FightingLucario
Water as a vapour (gas?) has to condense back to water, which can then become a solid if frozen.
When a substance changes from a liquid to a gas energy is absorbed. When a substance changes from a gas to a liquid energy is released.
when a water starts to boil it evaporates in to gas from gas to liquid
Color change Precipitate (cloudy) Bubbles - gas is produced.

Nitrogen can freeze anything and i think it is a frozen gas.
This change is called sublimation.
The two changes of state involved in freeze drying are melting and freezing.
Yes.
The gas exchange that takes place in the lungs are carbon dioxide and oxygen.
it is a atom cinetic with a gas plant and the enviroment
gas
It changes of state from solid directly into gas (vapor) without getting fluidised (by melting first). It is used in freeze-drying
