The last part is : what is the total energy transfer as HEAT in the isobaric process in joules?

initials 9. (6 points) A 1.00-mole sample of an ideal, monatomic gas, initially at temperature 450.0 K and pressure 1.40x 105 Pa, is compressed isobarically so that the final temperature decreases by 125 K (its final temperature is 325 K). Assume the molar specific heat at constant volume of this gas is the theoretically-derived K). value for a monatomic gas: Cv = (3/2) R. The universal gas constant is R = 8.314 J/(mol (a) Sketch this thermodynamic process on a PV- Diagram in the box to the right. The PV- Diagram must include labeled axes, labeled initial and final states (points), and a path with an arrow indicating direction. (b) What is the initial volume of the gas, and what is the final volume of the gas? (Please express the volumes in units of meters cubed.) m 3 i . Vinitial = m 3 ii. V final = (c) How much work (in joules) is done on the gas in this compression? d) What the change in internal energy of the gas (in joules)
