Question

An ideal monatomic gas at Pa = 3x10^5 N/m^2, Va = 0.06m^3, and T = 27C expands adiabatically tp Pb = 2x10^5 N/m^2 and Vb = 0.085m^3 and then isothermally to Vc = 0.1m^3. What are the final temperature, pressure, and work performed by the gas? Show these paths on a P-V diagram

Answer #1

Consider a Carnot cycle that goes isothermally from A
(pa,Va,Thot) to B (pb,
Vb ,Thot), adiabatically to C (pc,
Vc ,Tcool), isothermally to D (pd,
Vd ,Tcool), and adiabatically back to A
(pa,Va,Thot); pa is the
maximal pressure. (a) Sketch the pV diagram for this Carnot cycle.
(b) Calculate the change in entropy DS for the A-B isotherm,
calculate the change in entropy DS for the B-C adiabatic expansion.
(Hint: DS for adiabat B-C is not equal to zero; DS...

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...

2.00-mol of a monatomic ideal gas goes from State A to State D
via the path A→B→C→D:
State A PA=11.0atm, VA=13.00L
State B PB=11.0atm, VB=6.50L
State C PC=20.5atm, VC=6.50L
State D PD=20.5atm, VD=22.00L
Assume that the external pressure is constant during each step
and equals the final pressure of the gas for that step.
Calculate q for this process.
Calculate w for this process.

1. An ideal monatomic gas, with 24.05 moles, expands
adiabatically from 0.500m^3 to 1.75 m^3. IF the initial pressure
and temperature are 1.40x10^5 Pa and 350K, respectively, find the
change in internal energy of the gas if the final temperature of
the gas is 152K.

3. An ideal monatomic gas expands isothermally from .500 m3 to

a 2 mol ideal monatomic gas is carried through a cycle
from A to C. in state A it has a pressure of 2×10^5 Pa and a volume
of 0.010 m^3, then it increases its volume to 0.030 m^3 at constant
pressure to reach state B, then it reaches state C to a constant
volume decreasing its pressure qnd finally the gas isothermally

A mole of a monatomic ideal gas is taken from an initial
pressure p and volume V to a final pressure 3p and volume 3V by two
different processes: (I) It expands isothermally until its volume
is tripled, and then its pressure is increased at constant volume
to the final pressure. (II) It is compressed isothermally until its
pressure is tripled, and then its volume is increased at constant
pressure to the final volume. Show the path of each process...
