Question

What is the process of conversion of solid state directly to gaseous state called?
A) Evaporation B) Condensation C) Sublimation D) Distillation

Answer 1

Answer:

(C) Sublimation

Explanation:

Sublimation is the process of transformation directly from the solid phase to the gaseous phase, without passing through an intermediate liquid phase.

Answer 2

Answer:

C) Sublimation

Explanation:

Sublimation- It is the transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase.  

Condensation- It is the change of the physical state of matter from gas phase into liquid phase.

Evaporation is a type of vaporization of a liquid that occurs from the surface of a liquid into a gaseous phase that is not saturated with the evaporating substance.

Deposition is a thermodynamic process, a phase transition in which gas transforms into solid.

Melting (also known as fusion) is a physical process that results in the phase transition of a substance from a solid to a liquid.
