An ideal gas obeying kinetic theory of gases can be liquified, if

Options

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 liquified at any value of P and T .

Answer

D

Explanation

Ideal gas has no force of attraction and has no volume for molecules . Hence , it cannot be liquified at any point T and P
