A 3 mole sample ideal gas is confined in a cylinder that is carried through a closed cycle. The gas is initially at 70 atm and at 300 K. First, its pressure is tripled under constant volume. Then, it expands isothermally to its original pressure. Finally, the gas is compressed isobarically to its original volume (see the figure) . What was the net work done (in MJ) on the gas for this cycle? (Hint: clockwise cycle causes negative work done) (Answer 2 decimal places) 3P, Isothermal P V(L) Vc
A monatomic gas is take through a cycle from A to B to C and back to A. At A the pressure is 100,000 pa, the volume is 4.0 liters, and the temperature is 300K. The gas is compressed adiabatically until the volume is 1.0 liters (at B). How much energy was given to or removed from the gas during the adiabatic process?
A gas was taken through the cycle ABCA shown in the PV diagram below. The curve AB follows the equation PV=9200 where P in Pa and V in m3. On the figure below V1=6 m3 and P1=766.67 Pa. The internal energy at A equals that at B and twice that at C. The heat in J absorbed by the gas in the AB process equals: 28 C- B Vi
Which one of the following statements is true? (a) The path on a PV diagram always goes from the smaller volume to the larger volume. (b) The path on a PV diagram always goes from the smaller pressure to the larger pressure. (c) The area under the path on a PV diagram is always equal to the work done on a gas. (d) The area under the path on a PV diagram is always equal in magnitude to the work done on a gas.
In the figure below, the change in internal energy of a gas that is taken from A to C along the blue path is +870 J. The work done on the gas along the red path ABC is -520 J. (a) How much energy must be added to the system by heat as it goes from A through B to C? (b) If the pressure at point A is five times that of point C, what is the work done on the system in going from C to D? (c) What is the energy exchanged with the surroundings by heat as the gas goes from C to A along the green path? (d) If the change in internal energy in going from point D to point A is +555 J, how much energy must be added to the system by heat as it goes from point C to point D?
The graph shown is for a dilute gas that follows the clockwise path of quasi-static steps: isobaric expansion, isochoric reduction of pressure, isobaric compression, and isochoric increase in pressure. The vertical axis is shown in multiples of the pressure pp, where p=2.5atm, and the horizontal axis is shown in multiples of V, where V=4L.
