Question

Q.16
The values of critical temperature (TC) and
critical pressure (P) for some gases are given
below. Which of the gases can not be liquefied
at 100 K and 50 atm?
Gases (0) (ii) (iii) (iv)
Pc (atm) 2.2 14 35 45
T(K) 5.1 33 127 140
(A) (iv) only
(B) (i) only
(C) (i) and (ii) (D) (iii) and (iv)​

Answer 1

Answer:

C

Explanation:

Answer is option C because the given temperature is above their Critical Temperature which means that gases 1 & 2 cannot be liquified at any amount of pressure.

For the liquification of any gas T < Tc.
