Question
1. Two moles of a monatomic ideal gas such as helium is compressed adiabatically and
reversibly from a state (5.5 atm, 6.5 L) to a state with pressure 6.5 atm. For a monoatomic gas
y = 5/3.
(a) Find the volume of the gas after compression.
V final
L
(b) Find the work done by the gas in the process.
W=
L.atm
(c) Find the change in internal energy of the gas in the process.
AE int
=
L.atm
Check: What do you predict the signs of work change in internal energy to be? Do the
signs of work and change in internal energy match with your predictions?
