### Question 9.10

Posted: Sun Feb 04, 2018 3:30 pm
This isn't an assigned problem, but I just wanted to check if I was doing it correctly as it is another iteration of 9.9.

9.10: Calculate the entropy change associated with the isothermal compression of 4.80 mol of ideal gas atoms from 12.86 L to 4.80 L.

You would just use the equation nRln(V2/V1) where n is 4.80 mol and V2 is 4.80L and V1 is 12.86L.

Use the equation nRln(V2/V1)=$\Delta s$
n= 4.80 moles
V2= 4.80 moles
V1= 12.86
Expect a decrease in entropy because the volume decreased.
