	/// Example03: A Diesel Engine Cylinder
	/// Air at 20.0 C in the cylinder of a diesel engine is 
	/// compressed from an initial pressure of 1.0 atm and
	/// volume of 800.0 cm^3 to a volume of 60.0 cm^3. Assume
	/// that air behaves as an ideal gas with \gamma = 1.4 and
	/// that the compression is adiabatic. Find the final
	/// pressure and temperature of the air.
	/// p_f = 37.6 atm
	/// T_f = 553 C.
