Question

gas are liquefied under-
(a)low pressure high temperature
(b)low pressure low temperature
(c)high pressure low temperature
(d)high pressure high temperature

Answer 1

high pressure and low temp.

Answer 2

Answer: Option (c) is the correct answer.

Explanation:

When we provide high pressure and low temperature to a gas then due to high pressure its molecules come closer to each other.

And due to low temperature there occurs decrease in kinetic energy of the gas molecules. Hence, force of attraction between the molecules increases due to which gaseous state changes into liquid state.

Thus, we can conclude that gas are liquefied under high pressure low temperature.
