(a) How much work is required to compress 5.10 mol of air at 19.9°C and 1.00 atm to one-ninth of the original volume by an isothermal process? 27.29 kJ (b) How much work is required to produce the same compression in an adiabatic process? X No heat flows out of the system in an adiabatic process so the final temperature will be greater than the temperature in part (a). Would you expect a smaller amount of work to be required in this case? KJ (c) What is the final pressure in part (a)? x Note that you do not need to use your result from part (a) to solve this part of the problem. atm (d) What is the final pressure in part (b)? x Note that you do not need to use your result from part (b) to solve this part of the problem. atm
