Specific heat of a van der waals gas
WebThe van der Waals equation of state was designed to predict the relationship between pressure p, volume Vand temperature T for gases better than the Ideal Gas Law: gas The van der Waals parameters a and b have to be determined for each gas by comparing to experimental data. Consider the hypothetical gases X, Y and Z listed in the table below. In chemistry and thermodynamics, the Van der Waals equation (or Van der Waals equation of state) is an equation of state which extends the ideal gas law to include the effects of interaction between molecules of a gas, as well as accounting for the finite size of the molecules. The ideal gas law treats gas molecules as point particles that interact with thei…
