Half a mole of a perfect gas expands isothermally and at 298.15 K from a volume of 10 L to a volume of 20 L. (a) What is the change in the entropy of the gas? (b) How much work is done on the gas? (c) What is qsurr ? (d) What is the change in the entropy of the surroundings? (e) What is the change in the entropy of the system plus the surroundings? Now consider that the expansion...
A piston containing 0.75 moles of a perfect gas at 25 degrees C is moved isothermally from a starting volume of 8.305 L. Calculate the work in joules if the piston is moved irreversibly against a constant external pressure of 4.100 atm. We weren't giving final volume so I am unsure of what to do. I tried to use P1V1 = P2V2 because the final pressure is equal to external pressure in an irreversible process. But then my final volume...
