Unformatted text preview: Version 001 HW29 gavrin (25111) 1 This printout should have 14 questions. Multiplechoice questions may continue on the next column or page find all choices before answering. Compressed Helium 001 (part 1 of 2) 10.0 points Helium gas at T i = 18 C is compressed re versibly without heat loss to onefifth its ini tial volume. 1 = 1 . 67. What is its temperature after compression? Correct answer: 855 . 466 K. 002 (part 2 of 2) 10.0 points What if the gas is dry air (23 percent O 2 , 77 per N 2 )? 2 = 1 . 4. Correct answer: 553 . 963 K. Air in a Diesel Engine 003 (part 1 of 2) 10.0 points 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 ( = 1 . 40) and that the compression is adia batic and reversible, find the final pressure....
