how do you call the change from a gas to a solid?

Answer 1

Sublimation: From gas directly to solid without becoming liquid.
Sublimation: From solid directly to gas.

Answer 2

Sublimation of an element or substance is a conversion between the solid and the gas phases with no intermediate liquid stage. Sublimation is a phase transition that occurs at temperatures and pressures below the triple point (see phase diagram).

At normal pressures, most chemical compounds and elements possess three different states at different temperatures. In these cases the transition from the solid to the gaseous state requires an intermediate liquid state. However, for some elements or substances at some pressures the material may transition directly from solid to the gaseous state. Note that the pressure referred to here is the vapor pressure of the substance, not the total pressure of the entire system.

The opposite of sublimation is deposition. The formation of frost is an example of meteorological deposition.

Answer 3

The changes from a solid to a liquid to a gas or from a gas to a liquid to a solid are called a phase changes

Answer 4

Depends on whether the gas goes through the liquid state intermediately. If the gas goes directly to a solid, it is sublimation. If the gas goes through the liquid state intermediately, that change is condensation. The change from a liquid to a solid is a further condensation. or solidification.

Answer 5

The solid to gas transition is called sublimation
The GAS to SOLID transition is called DEPOSITION

Answer 6

It is called "reverse sublimation"

And from solid to gas progressive of forward sublimation.

Answer 7

As far as I know it is called freezing, just like from liquid to solid.

Answer 8

Sublimation - the term is the same in both senses of the transformation.

Answer 9

It is called deposition.

It is widely used in semiconductor technology to put down layers of material.

Answer 10

sublimation is again used here. It can be used in both cases.
