Transcribed Image Text:Consider a process that occurs at constant volume.
The volume of a gas in a cylinder is 4.50 L, the
temperature is 31.0 °C and before the position
of the piston was fixed, the system was in
equilibrium with an external pressure of 1.2 bar
(given by the sum of a 1 bar atmospheric pressure
and a 0.2 bar pressure due to a brick that rests on
top of the piston). The gas is heated slowly until the
temperature reaches 56.2 °C. Assume the gas
behaves ideally, and its heat capacity at constant
volume is: Cv,m = 20.79J/(K.mol)
