the process is called sublimation
When a gas changes directly to a solid it is called deposition.
When a gas changes directly to a solid it is called deposition.
That one is easy. It becomes a gas. That process is called "Vaporation". The steam that comes out of the water is the gas. It only becomes a gas when the water boils.
When a solid melts or changes to a liquid. When a liquid boils or changes to a gas. or the reverse when a gas condenses to a liquid or a liquid freezes to a solid. Also it is possible for a solid to go directly to a gas without passing through the liquid stage. This is called sublimation and can occur with sulfur when heated, or ice in the winter when the sun shines on it..
The name of the process in which a solid changes directly into a gas is called sublimation.
Iodine is a purple-black non metal that changes to a deep purple gas when heated.
They are not the same thing.When something changes directly from solid to gas, it is said to sublimate.When matter changes from gas to solid it is called deposition, or sometimes called desublimation.
sublimation
A phase change directly from a gas to a solid is called deposition.
It is called sublimation.
Because it changes directly from solid to gas when heated. It sublimes.
When a solid is heated and changes to a liquid, the phase change is called melting.
