A sample of gas follow process represented by `PV^(2)` = constant . Bulk modulus for this process is `B`, then which of the following graph is correct ?

Options

A.
B.
C.
D.

Answer

A, B, C

Explanation

`PV^(2)` = constant `implies P prop V^(-2) implies (DeltaP)/(P) = -2(DeltaV)/(V)`
`implies ` Bulk modulus
` K = (DeltaP)/(-(DeltaV)/(V)) = 2P`
As `PV = nRT` So `" "` `K prop (1)/(V^(2))` and `K prop T^(2)`
