Version 001 – HW29 – gavrin – (25111) 1 This print-out should have 14 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. CompressedHelium 001(part1of2)10.0points Helium gas at T i = 18 C is compressed re- versibly without heat loss to one-fifth its ini- tial volume. γ 1 = 1 . 67. What is its temperature after compression? Correct answer: 855 . 466 K. 002(part2of2)10.0points What if the gas is dry air (23 percent O 2 , 77 per N 2 )? γ 2 = 1 . 4. Correct answer: 553 . 963 K. AirinaDieselEngine 003(part1of2)10.0points Air in the cylinder of a diesel engine at 11 . 6 C is compressed from an initial pres- sure of 0 . 92 atm and of volume of 801 cm 3 to a volume of 88 . 7 cm 3 . Assuming that air behaves as an ideal gas ( γ = 1 . 40) and that the compression is adia- batic and reversible, find the final pressure. Correct answer: atm. 004(part2of2)10.0points Find the final temperature under the same assumptions as above.
