Question

Which Method is used To Liquefy Atmospheric Gases

Answer 1

$\huge\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\pink{R}}}}$

● To liquefy a gas we need to bring the gas molecules together very close to each other. This is achieved by compressing them using high pressures.

● At very high pressures, the boiling point of the liquid rises. So at practically achievable temperatures, the gases can liquefy and exist as liquids.

Answer 2

$\large\red{\textbf{\underline{\underline{Here\:is\:your\:Answer :- }}}}$

It can be achieved by either increasing the pressure or decreasing the temperature which ultimately leads to the reduction of spaces between molecules.
