The ideal gas law describes the relation- ship between pressure (P), temperature (7), volume (V), and the number of moles of gas (n). PV = nRT The additional symbol, R, represents the ideal gas constant. The ideal gas law is a good approximation of the behavior of gases when the pressure is low and the temperature is high. (What constitutes low pressure and high temperature varies with different gases.) In 1873, Johannes Diderik van der Waals (Figure P2.7) proposed a modified version of the ideal gas law that better models the behavior of real gases over a wider range of temperature and pressure. (p+ **) (v - nb) = nRT In this equation the additional variables a and b represent values characteristic of individual gases. Use both the ideal gas law and van der Waals' equation to calculate the temperature of water vapor (steam), given the following data.

Your solution should store the result in a variable called T_ideal. B) Use the more complicated van der Waals gas law to solve for T under the same conditions. Your solution should store the result in a variable called T_Waal
