IsothermalExpansion 001(part1of2)10.0points 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(part2of2)10.0points Determine the temperature of the gas. Correct answer: 370 . 379 K. Isothermalcompressionshorter 003(part1of2)10.0points 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 . 004(part2of2)10.0points Find the work done by the gas. Correct answer: - 7 . 43567 kJ. SerwayCP1207 005(part1of2)10.0points Gas in a container is at a pressure of 2 . 3 atm and a volume of 8 m 3 .
