A sample of methane of mass 4.50 g occupies 12.7 dm^3 at 310 K. a) Calculate the work done when the gas expands isothermally against a constant external pressure of 30.0 kPa until its volume has increased by 3.3 dm^3. (Answer: -99 J) b) Calculate the work that would be done if the same expansion occurs isothermally and reversibly. (Answer: -167 J)
