Question: a gas with the properties of air moves from state...
A gas with the properties of air moves from state A to State B as defined by the pressure
and specific volume at these two end states. These two states are connected by a straight
line segment on a P-v diagram. The starting pressure is 1,000,000 Pa and 10 kg/m3. The
end state is 100,000 Pa and 1.2 kg/m3.
Find the following:
a. The work done by the system on its surroundings during this process.
b. The change in the internal energy of the system during this process.
c. The thermal energy added or removed through the system boundary during this process.
d. If the system expands reversibly across a movable boundary surrounded by an atmosphere
with a constant pressure of 100,000 Pa, what is the net work available from the combined system
and its atmosphere in the form of mechanical shaft work?
e. What is the change in the enthalpy of the system?
f. What is the change in the entropy of the system?
