Answer» (P + a/V^2) (V - b) = RTP is pressure, V is volume and T is temperature.[P] = [F/A] = [MLT^−2/L^2] = [ML^−1T^−2][V] = [L^3]We cannot add or subtract quantities of different dimensions. Therefore[P] = [a/V^2] ⇒ [a] = [PV^2] = [ML^−1T^−2L^6] = [M L^5T^−2]∴ [a] = [M L^5T^−2]Similarly,[b] = [V] = [L^3] |
