Give dimension of a and b in Vander Waal Equation |
|
Answer» (P + a/V2) (V - b) = RTP is pressure, V is volume and T is temperature.[P] = [F/A] = [MLT −2/L2] = [ML−1T −2][V] = [L3]We cannot add or subtract quantities of different dimensions. Therefore[P] = [a/V2] ⇒ [a] = [PV2] = [ML−1T −2 L6] = [M L5 T −2]∴ [a] = [M L5 T −2]Similarly,[b] = [V] = [L3] Pressure and volume |
