How does positional entropy differ from thermal entropy?

Hello!

Positional entropy refers to the number of molecular positions or arrangements that a system can have, whereas thermal entropy refers to the amount of thermal energy that is not available for any useful work.

Hi I was wondering if you could elaborate on thermal entropy and what you mean by useful work?
