The equation of a state of a real gas is given by `(P + (a)/(V^(2))) (V - b) = RT`, where `T` is absolute temperature, `P` is pressure, `V` is volume and `R` is universal gas constant. What are the dimensions of constant `a` and `b` ? |

Answer» The terms in addition or subtraction have same `unit//dimension`. Dimension of `(a)/(V^(2))`= dimensions of `P` `(a)/([L^(6)]) = [ML^(-1) T^(-2)]` Dimensions of `a = [ML^(5) T^(-2)]` Dimensions of b = dimensions of `V` Dimension of `b = [L^(3)]` |
