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

\begin{align} H \equiv \sum_{\zeta =1}^{10} \Delta n^{\zeta} U^{\zeta} \end{align}

is called the enthalpy of $\sf{P }$. Enthalpy is conserved when compound quarks are formed or decomposed because quarks are indestructible and enthalpy is defined by sums and differences of quark coefficients. Also, the hypothesis of conjugate symmetry implies that the internal energies of ordinary-quarks and anti-quarks are the same. Then since the net number of quarks $\Delta n$ in particle $\sf{P }$ and its anti-particle $\overline{\sf{P}}$ are related as $\rm{\Delta} \it{n} ^{\sf{Z}} ( \sf{P} ) = - \rm{\Delta} \it{n}^{\sf{Z}} ( \sf{\overline{P}} )$ for any type of quark $\sf{Z}$, 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 are objectified from thermal, visual and somatic sensations. And the internal energy is defined by the magnitude of a perception. So enthalpy characterizes awareness of all these sensations, net left-side from right.

 Next step: starting on time.
