PHY 241 Work Done by a Non-Ideal Gas As mentioned when we discussed the assumptions of the ideal gas model, this model has some non- physical consequences. For example, a real-world gas is not infinitely compressible. The first correction to the ideal gas law accounts for the fact that there is a minimum volume that you can compress a gas into: P(V - b) = Nk_BT Where $b$ is a constant (which depends on the element(s) from which the gas is composed) that represents the minimum volume that can be occupied by a molecule of gas. Determine the work done by the gas described by this equation of state as the gas changes volume isothermally from $V_i$ to $V_f$.

correction to the ideal gas law accounts for the fact that there is a minimum volume that you can
compress a gas into:
P(V - b) = Nk_BT
Where $b$ is a constant (which depends on the element(s) from which the gas is composed) that
represents the minimum volume that can be occupied by a molecule of gas. Determine the work done
