Enthalpy is basically the potential heat stored in chemical bonds... right?

What I like about enthalpy is that if you put energy into something then its enthalpy increases linearly regardless of its state and it's nearly identical to the energy put in.

As I understand it, Entropy does change when you fuck around with stuff, but it's not linearly related to either temperature or entropy and it's so little energy that as a person who rounds to the nearest whole number on principle find very hard to care about, but I acknowledge it exists.
It's energy lost and cannot be used for work. So you're losing energy to entropy even in an ideal closed system when you're manipulating gasses - heating up, compressing, expanding... you always lose to entropy, but it's very little compared to the overall usable energy of the system.

I get confusing information about this, so I'll just leave it for MMM to correct me.
