Question

state the conditions necessary to liquefy gases

Answer 1

Hi friend,

Liquiefing gas means changing of the substances in gaseous states are changed into liquid state.

To liquefy gas we must-

<>Decrease temperature
<>Increase pressure

By doing this the molecules of gas will come closer to each other and temperature is reduced so it will remove the enough energy to convert gas into liquid state. Thomas Andrews did work on liquefaction of gases like carbon dioxide.

Hope it helps....
