Now here we're going to say that there are three main factors that can increase my entropy. The first one is my molecular degrees of freedom. This is just the ways in which a molecule is free to move. Here we say the more ways a molecule can move, then the more entropic it is.
Next, the number of arrangements and this deals with molecular complexity and mass. When we say molecular complexity, it's just the number of atoms in a substance. So for example, let's say it gave us Chapter 4, which is methane versus ethane, which is chapter three, Chapter 3. This has five total atoms in IT1 carbon and four hydrogens. And this one here has 8 total atoms in it, 6 hydrogens, 2 carbons. That thing is more complex, therefore it's more entropic. More atom just means, more arrangements, more ways they can move, more ways they can position themselves.
Now connected also to this is Massachusetts. The greater the mass, the greater the complexity, the more entropic it can be as well. Finally, we can look at the number of moles of substances. More moles, more possibilities, more chaos, more disorder, an increase in entropy. So keep in mind these three different factors and how they can themselves increase our entropy overall.
