Thermodynamics
A monatomic, ideal gas is in a sealed container (the number of gas molecules is always constant);
the initial pressure is P_{1} = 1.14 x 10^{5} Pa and the initial volume is
V_{2} = 0.0571 m^{3}.  First, the volume of the gas is decreased at a constant
pressure (at P_{1} = 1.14 x 10^{5} Pa) to a volume of
V_{1} = 0.0501 m^{3}.
 Second, the pressure of the gas is increased at a constant
volume (at V_{1} = 0.0501 m^{3}) to a pressure of
P_{2} = 1.48 x 10^{5} Pa.
 Third, the volume of the gas is increased at a constant
pressure (at P_{2} = 1.48 x 10^{5} Pa) back to the original volume of
V_{2} = 0.0571 m^{3}.
 Fourth, the pressure of the gas is decreased at a constant
volume (at V_{2} = 0.0571 m^{3}) to its original pressure of
P_{1} = 1.14 x 10^{5} Pa.
How much heat was added to (give as a
positive number) or removed from (give as a negative number) the system? (The gas constant R = 8.31 J/moleK.) Q = J
