A fixed mass of an ideal gas has volume
at pressure
and temperature
. The volume of the gas is reduced at constant pressure to
as shown in the figure below.
The final temperature of the gas is
.
Determine
the final temperature
of the gas
the external work done on the gas.
For this change in volume and temperature of the gas, the thermal energy transferred is
. Determine
, the change in internal energy of the gas.
