The van der waals equation for a gas is (P + a/v2)(V-b) = RT where P = Pressure, V = Volume, T = Temperature. Find the dimensions and SI units of a,b, and the Gas Constant R.

a = pv2
a =  [ML-1T-2][L3]2
a = [ ML5T-2 ]
b = v
b = [L3]

if the mass of an electron is 9.1*10-31 kg. if its K.E is 3*10-25 j. calculate its velocity?

P+a/v so a/v dimensionally should be equal to P Fistly find the dimension of P i.e. ML-1T-2 V2 is volume so a/V2 should be equal to P ie a=ML2T-2
