3) Oxygen gas is separated from the air by Fractional Distillation of Air.

    Step-1 Air is collected and is put into the setup.

    Step-2 Air, is first compressed and put in cooler, where Solid H2O and CO2 is removed

    Step-3 Then it undergoes further heating and other process to obtain Oxygen, Argon and Nitrogen.

In this way you can obtain Oxygen from air.

4) Four uses of Liquid Oxygen are:-

   a) It is used in Missile and rockets, where it reacts with Hydrogen gas and produces a lot of thrust

  b) It is also used in Health and care. In case of Breathlessness, a person is put on ventilator, where this pure oxygen is directly supplied to the person's lungs.

  c) Oxygen has a lot of industrial use also, like in Steel Factories

  d) It is also used to generate energy at times.

5) We can play a major role in increasing the level of Oxygen by following the given steps:-

a) Planting more and more trees
