Temperature dependence of liquid volume

It is shown that the temperature dependence of the liquid volume is well described by the equation \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$ V = A + BT + CT^2 + V_e \exp ( - E/RT), $$\end{document} where A, B, C, Ve, and E are constants. This equation reflects two processes owing to which the liquid volume increases with temperature, namely, anharmonic oscillations of molecules and formation of “holes.”
