Question

ice floats in water but sinks in cooking oil

Answer 1

Ice floats in water but sinks in cooking oil because the density of water is more than density of ice so it floats in ice but the density of cooking oil is less than the density of ice so ice sinks in water

Answer 2

Ice floats in water because the density of ice is 0.9167 g/cm3 , that is less than the density of water (1 g/cm3 ).
Both oil and ice are slippery , but this is where the similarity ends.Oil and ice have very little in common . Actually , oil dies not like ice, or more specifically melted ice,water. Oil is known as hydrophobic, meaning that it repels water. When ice cube is put in the oil, it begins to melt. It does not mix with the oil because it is hydrophobic. And so ice remains at the bottom. Density of cooking oil is 0.9167g/cm3 that is less than the density of ice (0.93g/cm3).So,ice sinks in cooking oil.
