Variation of internal energy with density of `1 "mole"` of monatomic gas is depicted in Fig. Corresponding variation of pressure with voluem can be depicted as (assume the curve is rectangular hyperbola) A. B. C. D.

Answer» Correct Answer - D
d. Sincee `U rho` = constant,
`(P)/(rho) = (RT)/(M)`
`P =` constant since `rho` is increasing, therefore `V` is decreasing.
