Let particle $\sf{P }$ be characterized by its quark coefficients $\Delta n$ and their associated internal energies $U$. Recall that $\zeta$ is an index that notes quark-type. Definition: the **enthalpy** of $\sf{P }$ is

$\begin{align} H \equiv \sum_{\zeta =1}^{16} \Delta n^{\zeta} U^{\zeta} \end{align}$

We also make use of a partial sum over just chemical quarks

$\begin{align} H_{\sf{chem}} \equiv \sum_{\zeta =11}^{16} \Delta n^{\zeta} U^{\zeta} \end{align}$

Enthalpy is conserved when compound quarks are formed or decomposed because quarks are indestructible and the enthalpy is defined by sums and differences of quark coefficients.

The assumption of conjugate symmetry requires that the internal energies of ordinary-quarks and anti-quarks are the same as each other

$U^{\zeta} = U^{\overline{\zeta}}$

Also the net number of quarks $\Delta n$ in particle $\sf{P }$ and its anti-particle $\overline{\sf{P}}$ are related by

$\rm{\Delta} \it{n} ^\zeta \sf{ ( P ) } = - \rm{\Delta} \it{n}^{\zeta} \sf{( \overline{P} ) }$

So the enthalpies of particles and anti-particles are related as

$H \left( \sf{P} \right) = - H \left( \sf{\overline{P}} \right)$

Sensory Interpretation: Thermodynamic quarks and chemical quarks are objectified from thermal, visual, somatic and taste sensations. And the internal energy is defined by the magnitude of a perception. So enthalpy characterizes an awareness of the magnitude for *all* these sensations, net left-side from right.
