Question

Consider the following four-process cycle that is carried out on a system of monatomic ideal gas, starting from state 1 in which the pressure is 88.0 kPa and the volume is 3.00 liters.

Process A is an isothermal process that triples the
volume;

process B is a constant volume process that returns the system to a
pressure of 88.0 kPa;

process C is an isothermal process that returns the system to a
volume of 3.00 liters;

and process D is a constant volume process that returns the system
to state 1.

You should sketch a *P*-*V* diagram for this
cycle, to help you understand it.

Complete the table below. For each process, and the entire cycle,
find the heat added to the gas, the work done by the gas, and the
change in internal energy.

Answer #1

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...

A cylinder of monatomic ideal gas is sealed in a cylinder by a
piston. Initially, the gas occupies a volume of 3.00 L and the
pressure is initially 105 kPa. The cylinder is placed in an oven
that maintains the temperature at a constant value. 65.0 J of work
is then done on the piston, compressing the gas (in other words,
the gas does −65.0 J of work). The work is done very slowly so that
the gas maintains a...

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...

a.) In an Isothermal process the temperature stays thes same as
the volume and pressure are allowed to change. In such a proces the
work is found by W=nRTln (VfVi), with n as the number of moles, R
as the constant 8.31 J/mole*K . How much work is done in an
isothermal process of an ideal gas starting at a pressure of 2.10E2
kPa, and 0.0360 m3 volume as it expands to a volume of 0.165
m3?
b.) If the...

Consider a process carried out on 1.00 mol of a monatomic ideal
gas by the following two different pathways. The first pathway
is A (3.00 atm, 20.0 L) to C (1.00 atm, 20.0 L) to D (1.00 atm,
50.0 L); and the second pathway is A (3.00 atm, 20.0 L) to B
(3.00
atm, 50.0 L) to D (1.00 atm, 50.0 L). In each case, the gas is
taken from state A to state D.

The working substance of an engine is 1.00 mol of a monatomic
ideal gas. The cycle begins at P1=1.00 atm and V1=24.6L. The gas is
heated at constant volume to P2=2.00atm. It then expands at
constant pressure until its volume is 49.2L. The gas is then cooled
at constant volume until its pressure is again 1.00 atm. It is then
compressed at constant pressure to its original state. All the
steps are quasi-static and reversible.
Calculate the TOTAL work done...

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...
