The state of an ideal gas can be represented by a point on a PV
(pressure-volume) diagram. If you know the quantity of gas, n, a
unique point in pressure (P) and volume (V) can be used to
determine a temperature (T). Each point on a PV diagram also has a
single internal energy (U) assigned to it. If a process starts at a
point and returns to that same point on a PV diagram, it returns to
the same...

Consider an ideal gas that initially has a pressure of 1909kPa and a volume of 11.0L. The gas in compressed at constant pressure to a volume of 7.00L. Heat is then added at constant volume until the pressure reaches 3 ⇥ 103kPa. Draw the process on a P-V diagram and calculate: the work done; the change in internal energy; the heat flow (into/out of the gas)

V. PV diagrams Ideal gas processes are often represented graphically. For instance, a PV diagram is a graph of pressure versus volume for a given sample of gas. A single point on the graph represents simultancously measured values of pressure and volume These values define a state of the gas A.

ss.19.2.8
The picture shows a circular process of an ideal monatomic gas
in the amount of 1 mole in the coordinates (p,V). In which sections
of the process does the gas absorb heat and in which sections does
it release heat? Find the efficiency of the cycle. The pressures
p1, p2 and volumes V1, V2 are given.
a clear explanation is highly appreciated! Thanks!

Constants Calculate the total work done by the gas in the process. Express your answer to two significant figures and include the appropriate units. Consider the following two-step process. Heat allowed to flow out of an ideal gas at constant volume so that its pressure drops from P = 2.9 atm to P2 = 1.3 atm. Then the gas expands at constant pressure, from a volume of V1 = 6.0 L to V2 = 9.3 L , where the temperature...

One mole of an ideal mono-atomic gas is in a state A characterized by a temperature TA. The gas is then subjected to a succession of three quasi-static reversible processes: An isothermal expansion A → B, which increases the volume by a factor y. The expansion factor is therefore y = VB / VA> 1. An adiabatic compression B → C which increases the pressure by a factor w. The compression factor is w = pC / pB> 1. A...
