### Boltzmann equation: positional entropy or thermal entropy?

I get that entropy has two parts: thermal entropy and positional entropy
I'm just confused that for the one with Boltzmann equation, is that positional or thermal?

According to the textbook the Boltzmann equation calculates "statistical entropy," which I think takes both positional and thermal entropy into account.

I also read somewhere that it "quantifies the entropy of a system", what exactly does that mean in terms of types of entropy?

For Miranda, quantifying simply means putting a number to the amount of energy. If you quantify entropy you add the units Joules per degree Kelvin. For any entropy, both positional and thermal you can quantify it. When you quantify the amount of energy you can evaluate how it was used in reactions.
