Answer 2

Answer:

Gases can be obtained from air by the process of  Fractional distillation

Explanation:

Fractional distillation :By fractional distillation, air is broken down into its constituents (oxygen, nitrogen, argon, etc.) which are used for industrial use. In the field of industrial chemistry, liquids produced by chemical synthesis are distilled and separated.

Condensation: The phenomenon of gas becoming liquid is called condensation. It is the opposite of evaporation. It is often used only in the context of the water cycle. Rain is also a type of condensation

Crystallization- It is the method of separation by which particles with regular geometry of pure substance are obtained from the solution of an impure solid substance soluble in a liquid. To obtain a pure substance, as many impure substances as can be dissolved in the hot liquid are dissolved.

Evaporation: Evaporation is the process in which an element or compound changes into a gas state. In chemistry, the process of change from liquid to vapor is called 'evaporation'. The change of any element or compound present on the earth from liquid state to gas state is called vaporization or vaporisation.
