Does the value of b (Volume Correction) depend on temperature?
If yes, shouldn't the critical constants too depend on temp. as Pc= 8a/27Rb, Vc= 3b?
If no., how come do the 2nd, 3rd, 4th.. virial coefficients depend on temp. as they equal b^2, b^3 and so on.
Also, is the volume of a single gas molecule dependent on temp.?
