Self-Test 9.10A

Postby Tim Nguyen 2J » Sat Feb 10, 2018 8:23 am

Calculate the entropy of a sample of a solid in which the molecules may be found in any one of three orientations with the same energy. Suppose there are 30 molecules in the sample.

Using Boltzmann's formula, the value for W would be 30^3? How would you arrive to the answer of 4.5 x 10^-22 J/K?

Use S = k ln W where W = 330

As I discussed in class: W is the number of possible states to the power of N where N is the number of particles, molecules, etc.

Hope this helps.
