Question

list 2 ways by which gas can be converted into water?

Answer 1

condensation and comprretion is the right answer

Answer 2

Liquefaction of a gas occurs when its molecules are pushed closer together. The molecules of any gas are relatively far apart from each other, while the molecules of a liquid are relatively close together. Gas molecules can be squeezed together by one of two methods: by increasing the pressure on the gas or by lowering the temperature of the gas.

That means that no amount of pressure applied to a sample of carbon dioxide gas at or above 88°F will cause the gas to liquefy. At or below that temperature, however, the gas can be liquefied provided sufficient pressure is applied.
