Question

A cylinder containing 3.0 moles of a monatomic, ideal gas begins
at a pressure of

2.0 × 10^{5} Pa, with a volume of 0.0365 m^{3}. The
gas then goes through the following three processes, which comprise
a thermal cycle:

- The gas is expanded isothermally, to twice its original volume.
- The gas is cooled isobarically, back to its original volume.
- The gas is heated isochorically, up to its original pressure.

(**a**) Find the initial temperature of the gas, in
Kelvin.

(**b**) Find the work done by the gas during each
of the above processes.

(**c**) Find the heat added to the gas during each
of the above processes.

(**d**) Find the net work done by the gas during
the above cycle.

(**e**) Find the net heat added to the gas during
the above cycle.

**I already have answers to a-c just need help with d. And
e.**

Answer #1

. A container has n = 3 moles of a monoatomic ideal gas at a
temperature of 330 K and an initial pressure of three times the
atmospheric pressure. The gas is taken through the following
thermodynamic cycle: 1.- The gas is expanded isobarically (constant
pressure) to Vf = 2.5∙Vi. 2.- The pressure of the gas is decreased
isochorically (constant volume) to half of the initial value. 3.-
The gas is compressed isobarically back to its initial volume. 4.-
The...

2.)1.0 mol sample of an ideal monatomic gas originally at a
pressure of 1 atm undergoes a 3-step process as follows:
(i) It expands
adiabatically from T1 = 588 K to T2 = 389 K
(ii) It is compressed at
constant pressure until its temperature reaches T3 K
(iii) It then returns to its
original pressure and temperature by a constant volume process.
A). Plot these processes on a PV diagram
B). Determine the temperature T3
C)....

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
compounded solwly to its original volume closing the cycle. the
heat of the fas in the complete...
