An unknown number of moles of an ideal monoatomic gas expand reversibly from Vi = 3.10 m3 to Vf = 4.00 m3, at a constant pressure of 1.47 atm and an initial temperature of 300 K. a. Find the number of moles of gas.         185 b. Find the final temperature of the gas K.          387 c. Calculate the work done by the gas.

Look at the P-V diagram below (Diagram 1). Calculate the work done by the gas for the paths A, B and C. Assume that in Diagram 1, P1 = 1 atm, P2 = 4 atm, V1 = 5 L, V2 = 15 L. a) WA = 1013 J, WB = 0, WC = -2533 J b) WA = 0.01 J, WB = 0, WC = -0.025 J     c) WA = 2533 J, WB = 0, WC = -1013 J Calculate the work done by the gas for the path AB in Diagram 2. Use the data: P1 = 1 atm, P2 = 4 atm, V1 = 5 L, V2 = 20 L. (Path AB is an "isothermal" which means the temperature T is constant on this path). a) 0.012 J b) 1220 J                           c) 0.0278 J                      d) 2809 J

⦁    When a certain quantity of helium gas contained inside and engine cylinder combusts, the expanding gas causes the 12-cm-radius piston to move outward by 10.0 cm. If the gas remains at a pressure of 120 kPa for this process, what is the heat transfer? (See the diagram at the top of the next page.)⦁    1,960 J⦁    1,660 J⦁    1,360 J⦁    1,060 J⦁    760 J
