Physics 2213 Homework #3 Fall 2008 Read: Chapter 18.4, 19.1-19.8 For study: Q's #Q19.4, 5, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18 (not quizzed) E's & P's #18.43, 19.3, 4, 13, 17, 27, 33, 35, 43, 64, 65 To be prepared for your 2nd discussion section the week of September 15-19: #18.41 [Heat Capacities] #19.34 [Ferrari Engine] #19.41 [Air Process] #19.51 [Non-ideal Gas] #19.57 [Chinook/Santa Ana] #19.66 [Comparing Thermo. Processes] #1. [From Prelim 1, Fall’07] Monoatomic ideal gas (n moles) is undergoing a process whose PV diagram is shown on the right: first, the gas transitions from A to B at constant temperature, then B to C at constant pressure, and finally C to A at constant volume. (a) For each of the three steps AB, BC, and CA, state whether heat flows INTO the gas, OUT of the gas, or

Unformatted text preview: DOES NOT FLOW. (b) The pressure and volume of the gas are measured to be P A and V A , respectively, at point A. The volume of the gas at point B is V B =10 V A , and the pressure is P B =0.1 P A ,. Calculate the work W done in the cycle ABCA. Express your answer in terms of P A , V A , and any necessary fundamental constants or pure numbers. (c) What is the total amount of heat that flows out of the gas during those parts of the cycle where heat is flowing OUT? Express your answer in terms of P A , V A , and any necessary fundamental constants or pure numbers. (d) What is the total amount of heat that flows into of the gas during those parts of the cycle where heat is flowing IN? Express your answer in terms of P A , V A , and any necessary fundamental constants or pure numbers. [ HINT : you can use your answers from (b) and (c) to get to the answer faster!]...
