The equations must be dimensionally consistent in order to be able to operate. Each term must have the same net dimensions and units in the equation.For example, the van der Waals equation is dimensionally consisten t. P+ (V-b)= RT v? P = Pressure kPa R = universal gas constant J/mol K T= absolute temperature K V = Specific Volume m /kg b = gas constant

Expert Solution
Step 1

Vander Waals equation studies the behavior of real gases. This Vander Waal equation gives relation between pressure, volume and temperature conditions of real gas. The a and b are constants which explain real aspects in gas such as inter molecular forces and volume of molecules in the gas.These two quantities are negligible in Ideal gas
