Question

A real gas has crititical temperature and critical pressure as 40 degree c and 10 atm res
pectively then liquefaction of gas is possible at

Answer 1

Answer:

25°C and 12 atm.

Explanation:

Since, the critical temperature and pressure are 40 and 10 respectively so the liquefaction is possible at the temperature which is lower than the critical temperature which here in the option is only 25 degree Celsius.

While the pressure must be less or equal to the critical pressure of the gas for the liquefaction to take place.
