Question

The process in which a substance changes from a gaseous state to the liquid state is

A. absolute zero.
B. condensation.
C. critical temperature.
D. evaporation.

Answer 1

B. Condensation is the process in which a substance changes from a gaseous state to the liquid state.

Answer 2

Answer : The correct option is, (C) condensation

Explanation :

Condensation : It is a type of process where the substance changes their phase from gaseous state to liquid state.

Evaporation : It is a type of process where the substance changes their phase from liquid state to gaseous state.

Critical temperature : It is the temperature at and above which the gas can not be liquefied. It is represented by
`T_c`.

Absolute zero : The lowest theoretical temperature below which the molecules cease to exist.

Hence, the process in which a substance changes from a gaseous state to the liquid state is, condensation.
