I need help guys. I don't have any idea what to do for this question 10 grams of oxygen gas at an initial pressure of 2.5 atm. and a temperature of 25 C undergoes an isochoric cooling until the pressure is halved. (a). What is the temperature at the end of the process? (b). How much work has been done in this step? Next, the gas is isothermally compressed to its original pressure. (c). What is the volume at the end of the compression? (d). How much work has been done in this step? Finally, the gas undergoes an isobaric expansion to its original volume. (e). How much work has been done in this step?ne in this step?
