Which of the following diagrams (figure) depicts ideal gas behaviour?

Options

A.
B.
C.
D.

Explanation

We know that ideal gas equation is
`pV =nRT`
(a) When pressure p = constant
From (i) volume `V prop` Temperature T
(b) When T = constant
From (i) pV = constant
So, the graph is rectangular hyperbola.
(C ) When V= Constant.
From(i) `p prop T`
So, the graph is straight line passes through the origin.
(d) From (i) `p V prop T`
`rArr " " (pV)/(T)=` constant
`rArr` So, the graph hence through origin.
So (d) is not correct.
