Question

Write the dimensional representation for torque. If (P + a/V2) (V-b) =RT, Where the difference symbols have their usual meaning then what are the dimensions of a and b

Answer 1

Answer:

1. Dimensional representation for Torque

Torque = Force × Distance = MLT^-2 × L = ML^2T^-2

2. (P+a/V^2) (V-b) = RT

According to dimensional analysis

Pressure, P = a/V^2, V= Volume

ML^-1T^-2 = a/L^6

a = ML^5T^-2

Also, Volume, V = b

b = L^3
