In a hand pump, an initial volume
of 84 cm3 of air at 0.90 atm
and 340 K quickly (adiabatically) compressed to a volume
of 20 cm3.
(a) What is the change in internal energy just after
compression?
(b) After a long time, the gas exchanges heat with its container
and surroundings, and returns to 340 K, while remaining
compressed to 20 cm3. What is the final internal energy
of the gas?
(c) What is the heat transferred?
