Anyone knows what this means? Something to do with Thermodynamics?

It's been posted in an obscure corner of the physics department forever and I think it'd be nice to know what the heck this is all about. Thanks!

Enthalpy and Gibbs free energy. The first one is the internal energy plus the energy necessary to displace a rabbit's volume worth of air. Gibbs free energy then subtracts from that the heat that will flow into the rabbit from he environment. The idea is that a wizard would require this amount of energy to create a bunny out of thin air.

It's a composite of two figures from Schroeder's Introduction to Thermal Physics: Figure 1.15 on page 33, and Figure 5.1 on page 150.

Thank you both. That's a really good way of quickly remembering what those energies can do.
