Homework Help: ap chemistry

Posted by cheri on Wednesday, October 31, 2012 at 6:06pm.

1.95 mol of an ideal gas at 300 K and 3.00
atm expands from 16 L to 28 L and a final
pressure of 1.20 atm in two steps:
(1) the gas is cooled at constant volume
until its pressure has fallen to 1.20 atm, and
(2) it is heated and allowed to expand
against a constant pressure of 1.20 atm un-
til its volume reaches 28 L.
Which of the following is CORRECT?
1. w = 0 for (1) and w = −1.46 kJ for (2)
2. w = −4.57 kJ for (1) and w = −1.46 kJ
for (2)
3. w = 0 for the overall process
4. w = −4.57 kJ for the overall process
5. w = −6.03 kJ for the overall process
