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.
