A particular thermodynamic cycle acting on a monatomic ideal gas (y = 1.67) includes an isobaric expansion, an isochoric cooling, and then a isothermic contraction. The PV diagram is shown in the image below. P V The isobaric expansion occurs at a pressure of 1.8 × 105 Pa and changes the volume of the gas from 6.7 x 10-2 m³ to 13.08 × 102m³.

An ideal monatomic gas undergoes changes in pressure and volume, as shown in the pV diagram below. The initial volume is 0.02 m3 and the final volume is 0.10 m3. The initial pressure is 1 atm and the final pressure is 2 atm. Recall that 1 atm = 101.3 kPa. (a) Calculate the magnitude, or absolute value, of the work done on the gas in this process. Answer = - 13429J (c) The initial temperature of the gas is 308 K. Calculate the temperature of the gas at the end of the process. Answer = 3080 k  Just need answer with the following: (d) What is the change in thermal energy for the gas in this process? (e) Calculate the quantity of heat transfer added to (positive) or removed from (negative) the gas during this process.
