Question

How does pressure help in liquefication of gas ? name two liquefied gases uesd in daily lofe ?

Answer 1

When gases are compressed, the pressure applied on the molecules is very high and the molecules come very close to each other. thus the gas changes into liquid state.This is because the molecules of gases are far apart from each other whereas the molecules of liquid are close to each other.Thus pressure helps in the liquefaction of gases

LPG (liquified petroleum gas ) amd CNG (compressed natural gas)
