For a certain gas which deviates a litlle from ideal behaviour, the values of density, were measured at different values of pressure, P. The plot of on the Y-axis versus P on the X- axis was nonlinear and had an intercept on the Y-axis,which was equal to
Ideal Gas Law in terms of density -
- wherein
where
d - density of gas
P - Pressure
R - Gas Constant
T - Temperature
M - Molar Mass
-
For constant pressure V T, hence linear dependence with the slope.
Therefore, Option(1) is correct.
