A fixed amount of ideal gas goes through a process abc. In state a, the temperature of the gas is 152°C, its pressure is 1.25 atm, and it occupies a volume of 0.250 m³. It then undergoes an isothermal expansion to state b that doubles its volume, followed by an isobaric compression back to its original volume at state c. (Hint: First show this process on a pV diagram.) The ideal gas constant is , and 1.00 atm = 1.01 × 10⁵ Pa.
(a) How many moles does this gas contain?
(b) What is the change in the internal energy of the gas between states a and b?
(c) What is the net work done on (or by) this gas during the entire process?
(d) What is the temperature of the gas in state c?
