Find the dimensions of a and b in the formula `[P + (a)/(V^(2))[V-b]] = RT` where P is pressure and V is the volume of the gas.

Text Solution

Verified by Experts

By the principle of homogeneity, `a//V^(2)` is of the dimensions of pressure a and b is of the dimensions of volume.
`[a] = ["pressure"] [V^(2)] = [ML^(-1)T^(-2)][L^(6)]=[ML^(5)T^(-2)]`
`[b]=[V]=[L^(3)]`
