• Resumen

  • The effect of density inversion on the convective flow of water in a spherical glass flask cooled with the help of an icewater 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.
