Pressure versus temperature graph of an ideal gas is shown in figure. Density of the gas at point A is `P_(0)`. Density at B will be A. `(3)/(4)rho_(0)`B. `(3)/(2)rho_(0)`C. `(4)/(3)rho_(0)`D. `2rho_(0)`

Answer» Correct Answer - B
`rho=(PM)/(RT)` or `rho prop(P)/(T)`
`((P)/(T))_(A)=(P_(0))/(T_(0))` and `((P)/(T))_(B)=((3)/(2))(P_(0))/(T_(0))`
`((P)/(T))_(B)=(3)/(2)((P)/(T))_(A) therefore rho_(B)=(3)/(2)rho_(A)=(3)/(2)rho_(0)`.
