A van der Waals gas undergoes a Joule-Thomson expansion process.
Obtain for this case the value of the inversion temperature and
discuss its dependence on volume to determine if this temperature
is unique.
Van der Waals Gases
Under what conditions of volume does a van der Waals gas behave
like an ideal gas? Use the van der Waals equation of state to
justify your answer.
In the van der Waals model of a gas, as compared to an ideal
gas,
a. Intermolecular forces decrease the pressure, but
finite molecular volume increases it
b. Both intermolecular forces and finite molecular
volume increase the pressure
c. Both intermolecular forces and finite molecular
volume decrease the pressure
d. Intermolecular forces increase the pressure, but
finite molecular volume decreases it
Use the van der Waals equation and the ideal gas equation to
calculate the volume of 1.000 mol of neon at a pressure of 500.0
bar and a temperature of 355.0 K. (Hint: One way to solve the van
der Waals equation for V is to use successive approximations. Use
the ideal gas law to get a preliminary estimate for V

Hydrogen, acting as a van der Waals gas (EOS shown below), is
compressed in an isothermal closed system process from 6.236m3/kg
to 0.629m3/kg at 300K. What is the change in specific entropy of
the gas? (use the entropy change relation in chapter 12)
P = RT/( v − b) − a/( v^2) (1)
a = 27R^2Tcrit^2/(64Pcrit) (2)
b = RTcrit/ (8Pcrit) (3)
Following example 12-7 in the book the change in internal energy
of a van der Waals gas for...
The van der Waals equation for 1 mole of gas is given by (p
+av-2)(v - b) = RT. In general, curves of p versus v
forvarious values of T exhibit a maximum and a minimum at the
twopoints where (δp/δv)T = 0. The maximum and minumum
coalesceinto a single point on that curve
where(δ2p/δv2)T = 0 inaddition to
(δp/δv)T = 0. This point is calledthe "critical point"
of the substance and its temperature,pressure, and molar volume are
denoted by...
For oxygen gas, the van der Waals equation of state achieves its
best fit for a=0.14 N⋅m^4/mol^2 and b=3.2×10^(−5) m^3/mol
1.Determine the pressure in 2.0 mol of the gas at 10 ∘C if its
volume is 0.24 L , calculated using the van der Waals equation.
2. Determine the pressure in 2.0 mol of the gas at 10 ∘C if its
volume is 0.24 L , calculated using the ideal gas law.
Why does a gas have more work when adjusted for idealness
via Van der Waals equation and Dieterici versus ideal gas equation.
I have solved a problem where the gas has more work done when
adjusting for idealness rather than just using the ideal gas
equation. Why, in terms of intramolecular or intermolecular forces
does this occur?
