Gravity causes a stratification of plasma which introduces a possibility for instabilities to set in. In what follows, we assume a stratified plasma with horizontal magnetic field, prescribed gravity and temperature profile. Several different possible thermodynamic properties of plasma are taken into consideration in discussions of their influence on distributions of mass density, and consequently of potential energy, with height, in order to estimate the free energy of the unperturbed system that might be released through induced plasma motions if the system is unstable to linear perturbations. Finally, the linear approximation and normal mode analysis are applied to derive analytical dispersion relation and instability criterion for a special and commonly used case when perturbations are taken adiabatic while the magnetized plasma is assumed ideal and acting as a perfect gas.
