Description
For many of our applications, we have an ideal gas but with a mean molecular weight that varies as a function of $(\rho, T)$. The temperature can be solved via root-finding on on a table of mean molecular weight.
We have this implemented in Quokka for our tabulated dilute plasma cooling, but it is not currently integrated with the EOS infrastructure. In the future, we should move this part of the code to Microphysics.

Research direction
Start by locating the existing tabulated dilute plasma cooling implementation in Quokka and the EOS infrastructure in Microphysics. Compare their interfaces and determine what must move or be integrated. Done means an ideal-gas EOS with mean molecular weight tabulated as a function of density and temperature is integrated into the Microphysics EOS infrastructure.
