An ideal gas absorbs 5.00 x 103 J of energy
while doing 2.00 x 103 J of work on the
environment during a constant pressure process.
(a) Compute the change in the internal energy of
the gas. (b) If the internal energy now drops by
4.50 x 103 J and 2.00 x 103 J is expelled from
the system, find the change in volume, assuming a
constant pressure process at 1.01 x 105 Pa
