Problem 39P
Compute the entropy of a mole of helium at room temperature and atmospheric pressure, pretending that all the atoms are distinguishable. Compare to the actual entropy, for indistinguishable atoms, computed in the text.
ANSWER:
Step 1
We have to find the entropy of helium atom at room temperature and atmospheric pressure.
The entropy of an ideal gas is given by
where V is the volume
U is the energy
N is the number of molecules
m is the mass of a single molecule
h is Planck’s constant.
