A gas can be liquefied at temperature T and pressure P if-

A

`T=T_(c),P lt P_(c)`

B

`T lt T_(c) , P gt P_(c)`

C

`T gt T_(c),P gt P_(c)`

D

`T gt T_(c), P lt P_(c)`

Text Solution

Verified by Experts

The correct Answer is:
B
Two important conditions for liquefying a gas are
(i) temperature should be lower than critical temperature
`(T lt T_(c))` and (ii) pressure should be greater than critical pressure `(P gt P_(c))`.
