Hello,
I've been recently learning thermodynamics and have some questions about entropy. First off, I understand that it is a statistical measure of disorder and uncertainty and understand the 2nd and 3rd laws fairly well.
My question pertains more to Gibb's Free Energy. As I've learned it, there is only a certain amount of usable energy that can be done as non-expansion work that is equal to enthalpy - temperature*entropy. Thus, I am querying if there is something more to entropy than statistic. Does a system that has increased in entropy increased in energy, and some type of energy that is bound to entropy only? Is the disorder increase related to this unusable energy? I guess I'm wondering if entropy is somehow physical rather than just mathematical.
