Question
For a real gas the P-V curve was experimentally plotted and it had the following appearance. With respect to liquifaction. Choose the correct statement.
Options
A.at T = 500 K, P = 40 atm, the state will be liquid.
B.at T = 300 K, P = 50 atm, the state will be gas
C.at T < 300 K, P > 20 atm, the state will be gas
D.at 300 K < T < 500 K, P > 50 atm, the state will be liquid.
Solution
(a) at T = 500 K, P = 40 atm corresponds to ′a′ substance - gas
(b) at T = 300 K, P = 50 atm corresponds to ′b′ substance - liquid
(c) at T < 300 K, P > 20 atm corresponds to ′c′ substance - liquid
(d) at T < 500 K, P > 50 atm corresponds to ′d′ substance - liquid
So, Answer (D)
