2- Consider natural gas with a molecular weight of 23.6 kg/kmol and a specific

heat, c, of 2.01 kJ/kg K. The gas is slowly compressed in a frictionless,

adiabatic process from an initial volume of 212 cm? to a final volume of 98

cm?. If the initial pressure is 39 kPa, and the initial temperature is 15 °C,

find the final temperature and pressure. Assume the mixture can be modeled

as an ideal gas.
