Van der Waal's equation for a gas is stated as, p =nRT/(V - nb)- a (n/V)^2. This equation reduces to the perfect gas equation, p =nRT/V when,
Van der Waal's equation for a gas is stated as,
$$\mathrm{p}=\frac{\mathrm{nRT}}{\mathrm{~V}-\mathrm{nb}}-\mathrm{a}\left(\frac{\mathrm{n}}{\mathrm{~V}}\right)^2 .
$$
This equation reduces to the perfect gas equation, $\displaystyle \mathrm{p}=\frac{\mathrm{nRT}}{\mathrm{V}}$ when ,
