  • question_answer
    An ideal gas obeying kinetic theory of gases can be liquefied if   [CBSE PMT 1995]

    A)                 Its temperature is more than critical temperature \[{{T}_{c}}\]

    B)                 Its pressure is more than critical pressure \[{{P}_{c}}\]

    C)                 Its pressure is more than \[{{P}_{c}}\] at a temperature less than \[{{T}_{c}}\]

    D)                 It cannot be liquefied at any value of P and T

    Correct Answer: D

    Solution :

                    Absence of inter molecular attraction ideal gas cannot be liquefied at any volume of P and T.
