In a lava lamp, a waxy fluid (say ρ= 1225[kg/m3]) is surrounded by another fluid (say ρ= 1200[kg/m3]), they are mutually insoluble, and they are heated by a lamp in the bottom of the apparatus. The densities of these materials are very similar, where the waxy one is greater at normal room temperature. As the liquids are heated, the waxy density becomes less than the surrounding fluid and it rises. What is the buoyant force on a spherical waxy blob,...
