Question

One
mole of an ideal gas at 25 degrees celsius and one atmosphere
pressure expands adiabatically to twice its original volume, then
compresses isothermally back to the original volume, then proceeds
isochorically back to the initial conditions. How much work is done
by the gas?

work done by the ideal gas.

Answer #1

A two mole sample of an ideal diatomic gas expands
slowly and adiabatically from a pressure of 5 atm. and a volume of
10 liters up to a final volume of 30 liters.
a) What is the final pressure of the gas ?,
b) Whatis the heat, work and internal energy?

One mole of an ideal gas at atmospheric pressure expands
isobarically from a volume of 1m3 to a volume of
2m3.
1 - Find the initial and final temperatures of the gas
2 - Find the work done by the gas
3 - Find the heat added to the gas

An ideal gas with γ = 1.400 expands adiabatically from a
pressure of 365.0 Pa and a volume of 70.00 m3 , doing 101.0 J of
work while expanding to a final volume. What is its final
pressure-volume product?

One-third mole of a monatomic ideal gas expands adiabatically
and does 640 J of work. By how many kelvins does its temperature
change? K
Specify whether the change is an increase or a decrease.

An ideal gas with ?=1.4 occupies 3.0L at 300 Kand
100kPa pressure and is compressed adiabatically until its volume is
2.0 L. It's then cooled at constant pressure until it reaches 300
K, then allowed to expand isothermally back to stateA.
Find the net work done on the gas and Vmin?

A cylinder containing 3.0 moles of a monatomic, ideal gas begins
at a pressure of
2.0 × 105 Pa, with a volume of 0.0365 m3. 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)...

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...

1 mole methane gas (NOT ideal gas) isothermally expands from
initial pressure of 5 bar to 1bar at 50oC. Estimate the ENTROPY
change (?S) for the gas using Lee/Kesler generalized correlation
tables

One mole of an ideal gas does 3000 J of work on its surroundings
as it expands isothermally to a final pressure of 1.00 atm and
volume of 25.0 L. Determine:
a) the initial volume ?
b) the temperature of the gas?
(Note: 1 atm = 1.01 x 105Pa, universal gas constant R
= 8.31 J/mol K, 1 L = 10-3m3)

A 2.00-mol sample of a diatomic ideal gas expands slowly and
adiabatically from a pressure of 5.04 atm and a volume of 13.0 L to
a final volume of 31.0 L.

atm
(b) What are the initial and final temperatures?
initial
K
final
K
(c) Find Q for the gas during this process.
