A piston/cylinder contains butane, C₄H₁₀, at 300°C, 100 kPa with a volume of 0.02 m³. The gas is now compressed slowly in an isothermal process to 300 kPa. A. Show that it is reasonable to assume that butane behaves as an ideal gas during this process. b. Determine the work done by the butane during the process.
