Question

Question 3

Which is the state change that occurs when a solid becomes a gas without becoming a liquid first?

1)vaporization

2)sublimation

3)deposition

4)freezing

Answer 1

Sublimation is the transition of a substance directly from solid to gas phase

Answer 2

Answer:

The process is 2) sublimation.

Explanation:

Sublimation is the progress of a substance straightforwardly changing from the solid state to the gas stage, without going through the liquid stage.  

Sublimation is a type of endothermic procedure that happens at temperatures and weights beneath a substance's "triple point" in its stage outline, which compares to the most reduced weight at which the substance can exist as a fluid. The turn around the procedure of sublimation is desublimation, in which a substance passes legitimately from a gas to a strong stage.
