We now consider two moles of ideal gas at the same initial state (3.0 l at 273 k). this time, we will first perform an isobaric compression, then an isothermal expansion to bring the gas to the final state with the same volume of 3.0 l, and at temperature 90.0 k. hint for part (a), solve the ideal gas law for the volume after the compression, and use this value to find the work done. note that you are given the initial temperature and the number of moles. for part (b), use the volume you calculated for part (a) and the final temperature in the equation for work for an isothermal process. click the hint button again to remove this hint. (a) how much work (in j) is done on the gas during the isobaric compression? wcompression = j (b) how much work (in j) is done on the gas during the isothermal expansion?
