Thermodynamics
A monatomic, ideal gas is in a sealed container (the number of gas molecules is always constant);
the initial pressure is P1 = 1.14 x 105 Pa and the initial volume is
V2 = 0.0571 m3. - First, the volume of the gas is decreased at a constant
pressure (at P1 = 1.14 x 105 Pa) to a volume of
V1 = 0.0501 m3.
- Second, the pressure of the gas is increased at a constant
volume (at V1 = 0.0501 m3) to a pressure of
P2 = 1.48 x 105 Pa.
- Third, the volume of the gas is increased at a constant
pressure (at P2 = 1.48 x 105 Pa) back to the original volume of
V2 = 0.0571 m3.
- Fourth, the pressure of the gas is decreased at a constant
volume (at V2 = 0.0571 m3) to its original pressure of
P1 = 1.14 x 105 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/mole-K.) Q = J
