Question

A real gas has critical temperature and critical pressure as 40°C and 10 atm respectively, then liquification of gas is possible at
1)50°C and 8 atm
2)45°C and 8 atm
3)25°C and 12 atm
4)45°C and 12 atm

Answer 1

Answer:

Option C 25 degrees and 12 atm

Explanation:

Answer 2

Answer:25°c and 12 atm.

Explanation: For liquifaction, required temperature should be less than Tc and required pressure should be higher than Pc. So, the above mentioned answer is correct. Hope it helps.
