Multiplechoice questions may continue on the next column or page find all choices before answering. 001 (part 1 of 2) 10.0 points Given: R = 8 . 31451 J / K mol . How much work is done by the steam when 1 . 1 mol of water at 100 C boils and becomes 1 . 1 mol of steam at 100 C at 1 . 3 atm pressure? Answer in units of J. 002 (part 2 of 2) 10.0 points Find the change in internal energy of the steam as it vaporizes. Consider the steam to be an ideal gas with heat of vaporization 2 . 26 10 6 J / kg. Answer in units of kJ. 003 10.0 points One mole of an ideal gas is heated at constant pressure so that its temperature increases by a factor of 8. Then the gas is heated at constant temperature so that its volume increases by a factor of 8. Find the ratio of the work done during the isothermal process to that done during the isobaric process....
