Question

rockets carry liquid oxygen . why they do not carry oxygen in gaseous form

Answer 1

because liquid is MUCH more dense, in gaseous form might need to be 10x as big

or

Oxygen as fuel to react with hydrogen can be stored more efficiently in liquid form as it is far more dense than in a gaseous form. In addition to this the oxygen will react with the hydrogen fuel and upon releasing energy as thrust will also generate some water (Two hydrogen, one oxygen) in which the astronauts can (obviously) drink later

or

Liquid form occupies less volume than gaseous form.


hope its helpfull

Answer 2

Answer:

Density

Explanation:

Oxygen as fuel to react with hydrogen can be stored more efficiently in liquid form as it is far more dense than in a gaseous form. ... As O2 is stored at high pressure in the containers, so more O2 can be stored in form of liquid than in form of gas.
