Question

Select the one that when used would be
considered as best condition for liquification of
a gas.
(a) Increasing the temperature.
(b) Decreasing the pressure.
(c) Increasing the pressure and decreasing the
temperature.
(d) Decreasing the pressure and increasing the
temperature.

Answer 1

Answer:

Decreasing the pressure and increasing the temperature is the best condition for liquification of a gas

Answer 2

Concept Introduction: All substances can be crystallized.

Explanation:

We have been Given: Select the one that when used would be

considered as best condition for liquification of

a gas.

(a) Increasing the temperature.

(b) Decreasing the pressure.

(c) Increasing the pressure and decreasing the

temperature.

(d) Decreasing the pressure and increasing the

temperature.

We have to Find: The correct answer.

The correct option is Option No. D, Decreasing the pressure and increasing the temperature. Crystallization or crystallisation is the process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some of the ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas. Attributes of the resulting crystal depend largely on factors such as temperature, air pressure, and in the case of liquid crystals, time of fluid evaporation.

Final Answer: The correct option is Option No. D, Decreasing the pressure and increasing the temperature.
