FORMULAS

Thermal energy of ideal monatomic gas:

\begin{displaymath}U = {3\over 2} NkT = {3\over 2} nRT\end{displaymath}

Specific heat:

\begin{displaymath}c = {\Delta Q\over m\Delta T}\end{displaymath}

Stefan-Boltzmann equation:

\begin{displaymath}{\Delta Q\over \Delta t} = e\sigma A T^4\end{displaymath}

where e is emissivity.
