Question

Pressure versus temperature graph of an ideal gas as shown in Fig.
Corresponding density `(rho)` versus volume `(V)` graph will be

A.
B.
C.
D.

Answer 1

Along process AB,CD temperature is constant (isothermal process) i.e. `Pprop(1)/(V), rhoprop(1)/(V)`
`rho-V` graph will be a rectangular hyperbola.
Along BC and DA,V is constant `rArr rho` is constant
