Question

What condition of temperature and pressure favors the liquefaction of gases?

Answer 1

• The process of converting gases to liquid is known as liquefaction.
• The space between gas particles is large and the force between them is negligible.
• When high pressure is applied, the particles will come closer by leaving less space between them.
• When they come close, they will lose their kinetic energy and a force of attraction comes into action.
• The particles will become closely packed and will be slowly converted to liquid.
• At lower temperatures, the kinetic energy of gases decreases so that their motion decreases.
• So, high pressure and low-temperature help in liquefaction.
