Which is/are correct for real gases?

Options

A. `underset(P rarr 0)(Lt)(PV_(m)) =` constant at constant high temperature
B. `underset(V_(m) rarr0)(Lt)(PV_(m)) =` constant at constant low temperature
C. `underset(P rarr 0)(Lt) ((PV_(m))/(RT)) =1` at high temperature
D. `underset(V rarr 0)(Lt) ((PV_(m))/(RT)) = R`

Answer

A, C

Explanation

Low `P` and high temperature gas behaves as an ideal gas.
`:. PV =` constant and `(PV_(m))/(RT) = 1`
