Question

See diagram 4.

58 moles of a diatomic ideal gas undergo three steps:

A to B is an isobaric (constant pressure P1 = 5.71x10^6 Pascal) expansion from volume V1 = 0.025 m3 to V2 = 0.661 m3.

B to C is isochoric (constant volume)

C to A is isothermal (constant T).

Find PC, the pressure at point C, in Pascals. Express in scientific notation.

Answer #1

21.3 moles of a diatomic ideal gas undergo three steps:
A to B is an isobaric (constant pressure P1
= 4.15x106 Pascal) expansion from volume
V1 = 0.0609 m3 to
V2 = 0.934 m3.

C to A is isothermal (constant T).
During the isobaric expansion from A to B: find Q, the heat
transferred, in Joules. Give your answer in scientific
notation.
NOTE: A positive sign means heat has
been added; a negative...

#4 A system containing 2.50 moles of an ideal gas for which =
20.79 JK-1mol-1 is taken through the
following cycles: (1) an isobaric expansion (P1 = 16.6
bar) from V1 = 1.00 L to V2 = 25.0 L; (2) an
isochoric cooling from T2 to the original temperature,
T1; followed by (3) an isothermal compression (at
temperature T1) to the original pressure P1
and volume V1.
A. Represent the above processes on a P-V diagram

A flask contains 99 moles of a monatomic ideal gas at pressure
6.79 atm and volume 29.3 liters (point A on the graph. Now, the gas
undergoes a cycle of three steps:
- First there is an isothermal expansion to pressure 3.71 atm
(point B on the graph).
- Next, there is an isochoric process in which the pressure is
raised to P1 (point C on the graph).
- Finally, there is an isobaric compression back to the original
state...

3.0 moles of an ideal gas are subjected to the following
processes. First the volume is tripled in an isobaric process. Then
it undergoes an isothermal process to a pressure of 9.0 kPa. The
volume is then cut in half in another isobaric process after being
tripled. Finally, it returns to the original state in an isochoric
process. (a) Draw a PV diagram of the cycle. Label each state
(vertex) with a letter (A, B, …) and each transition with...

A flask contains 90.7 moles of a monatomic ideal gas at pressure
5.64 atm and volume 40.1 liters (point A on the graph. Now, the gas
undergoes a cycle of three steps:
- First there is an isothermal expansion to pressure 3.79 atm
(point B on the graph).
- Next, there is an isochoric process in which the pressure is
raised to P1 (point C on the graph).
- Finally, there is an isobaric compression back to the original
state...

The number of moles in a sample of diatomic gas molecules is
such that nR = 300 J/K. The initial volume of this sample of gas is
Va, and its initial temperature is Ta =250 K. The volume of this
sample of gas is doubled (Vb =2 Va) in a constant pressure
(isobaric) process and its temperature increases to Tb. What is the
change in entropy DS of this gas sample as a result of the isobaric
expansion to a...

3 moles of a monoatomic ideal gas with Cv=(32)RT occupies a
volume of 3.2L at a pressure of 1.9atm at point A. The gas is
carried through a cycle consisting of three processes:
1. The gas is heated at constant pressure until its volume is 4.4L
at point B.
2. The gas is cooled at constant volume until the pressure
decreases to 1.2atm (C).
3. The gas undergoes an isothermal compression back to point
A.
Find W for the isochoric...

The above pV diagram shows the expansion of 5.0 moles of a
monatomic ideal gas from state a to state b. As shown in the
diagram, Pa = Pb = 600 Pa, Va = 3.0 m3, and Vb = 9.0 m3. The
pressure is then reduced to 200 Pa without changing the volume, as
the gas is taken from state b to state c.
c. Determine Q for the process bc.
d. Determine the change in thermal energy of the...

28 moles of an ideal gas with a molar specific heat at constant
volume of cv=3.2R is initially in state "A" at pressure 73390 Pa
and volume 1.0 m3.
The gas then expands isobarically to state "B" which has volume
2.6?3m3.
The gas then cools isochorically to state "C".
The gas finally returns from state "C" to "A" via an isothermal
process.
What is the adiabatic constant γ for this gas?
What is Q during the expansion from "A" to...
