Is it the same when matter changes from gas to solid as when something sublimates?

Answer 1

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.

Answer 2

No, the processes of matter changing from gas to solid and sublimation are different. When matter changes from gas to solid, it undergoes deposition, where gas particles lose energy to form a solid. Sublimation is the direct transition from a solid to a gas without passing through the liquid state.
