A flexible balloon contains 0.350 mol of hydrogen sulfide gas (H2S). Initially the gas has a volume of 7.0 103cm3 and a temperature of 27C. The gas first expands isobarically until the volume doubles. Then it expands adiabatically until the temperature returns to its initial state. Assume that the hydrogen sulfide can be treated as an ideal gas. a) Draw a PV-diagram of the process. b) What is the total heat supplied to the gas during the process? c) Calculate the change in internal energy of the gas. d) What is the total work done by the gas? e) What is the final volume?
