Cooling of Water in a Flask: Convection Currents in a Fluid with a Density Maximum

Physics Teacher, v48 n1 p60-62 Jan 2010
The effect of density inversion on the convective flow of water in a spherical glass flask cooled with the help of an ice-water bath is shown. The experiment was carried out by temperature measurements (cooling curves) taken at three different heights along the vertical diameter of the flask. Flows inside the flask are visualized by seeding the water with blue ink.
