Midterm

[Lily Benitez 2G]

Nanotechnologists have found ways to create and manipulate structures containing only a few molecules. However, orienting the molecules in specific ways to assemble such structures can be difficult. Calculate the entropy of a solid nano structure made of 64 molecules in which the molecules (i) are all aligned in the same direction; (ii) lie in any one of four orientations with the same energy.

How do we find Kb for part two?

[Alana Sur 3B]

Kb is boltzmann's constant, which is given in the equation sheet.
for part two, we calculate :
w = orientations ^ # of molecules.
delta S = Kb x w
delta S = (1.38x 10^-23) (4^64)

[Celio_G_Dis2C]

Kb is given already, it should be on the constant sheet
