Abstract
Natural convection of water in a cylindrical cavity with an open surface at a temperature of about 3.98°C (temperature of the maximum water density) is accompanied by typical anomalies on time dependences of temperatures of water layers. In particular, stabilization of temperature Tst is observed in the bottom region of the cavity and duration of such stabilization tst may reach several hours depending on the experimental conditions. The results for solutions of sodium chloride and ethanol at a relatively low rate of water cooling show that temperature Tst coincides with temperature Tmax corresponding to the maximum density of solutions.
