Unformatted text preview: Version 001 HW28 gavrin (25111) 1 This print-out should have 13 questions. Multiple-choice questions may continue on the next column or page find all choices before answering. Isothermal Expansion 001 (part 1 of 2) 10.0 points One mole of an ideal gas does 2163 J of work on the surroundings as it expands isother- mally to a final pressure of 1 . 6 atm and vol- ume of 19 L. Find the initial volume. The universal gas constant is 8 . 31451 J / K mol. Correct answer: 9 . 41267 L. 002 (part 2 of 2) 10.0 points Determine the temperature of the gas. Correct answer: 370 . 379 K. Isothermal compression shorter 003 (part 1 of 2) 10.0 points Two moles of helium gas initially at 320 K and 0 . 45 atm are compressed isothermally to 1 . 82 atm. Find the final volume of the gas. Assume that helium behaves as an ideal gas. The universal gas constant is 8 . 31451 J / K mol. Correct answer: 0 . 0288626 m 3 ....
