Question

Which of the following phase changes only occurs in solids possessing vapor pressures above atmospheric pressure and at ambient temperature?

a. Condensation
b. Melting
c. Sublimation
d. Deposition

Answer 1

Answer: The phase change process in which solids gets converted to gases is sublimation.

Step-by-step explanation:

For the given options:

Option a: Condensation

It is a type of process in which phase change occurs from gaseous state to liquid state at constant temperature.

`Gas\rightleftharpoons Liquid`

Option b: Melting

It is a type of process in which phase change occurs from solid state to liquid state at constant temperature.

`Solid\rightleftharpoons Liquid`

Option c: Sublimation

It is a type of process in which phase change occurs from solid state to gaseous state without passing through the liquid state at constant temperature.

`Solid\rightleftharpoons Gas`

Option d: Deposition

It is a type of process in which phase change occurs from gaseous state to solid state without passing through the liquid state at constant temperature.

`Gas\rightleftharpoons Solid`

Hence, the phase change process in which solids gets converted to gases is sublimation.
