General Question

Why do more massive elements or molecules have greater entropy?

Re: General Question  [ENDORSED]

Larger molecules tend to have greater entropy than smaller ones because heavier molecules have more vibrational energy states. In this way, the molecules have a greater number of possible positions they can take up. Using the formula S=k*lnW with W being the number of ways the atoms or molecules in a sample can be arranged and still give rise to the same total energy, we can see that the greater the number of positions, the higher the entropy. Hope that helps!
