'Negative heat capacity' in stratified fluids

In ’doubly nonequilibrium’ fluids (e.g., in temperature- and admixture-concentration-stratified solutions in the gravity field) situations may occur in which adding (extracting) heat can lower (raise) the temperature of the medium. Several simple examples of this phenomenon are considered.
