A well-insulated piston–cylinder assembly is connected to a CO2 supply line by a valve, as shown below. Initially there is no CO2 in the piston–cylinder assembly. The valve is then opened, and CO2 fl ows in. What is the temperature of the CO2 when the volume inside the piston– cylinder assembly reaches 0.1 m3? How much CO2 has entered the tank? Take CO2 to be an ideal gas, with a constant heat capacity of cP = 37 [J/ 1mol K2].
