Oil drop may……. On a hot water.

Assertion: Oil drops spread on cold water and remain as a drop on hot water. Reason : Surfnce tension of oil is less than cold water and more than that of hot water.

Oil spreads on cold water but remains as drop on hot water.

"On cold water oil spreads, but on hot water it remains in the form of drops." Why?

A water drop takes the shape of a sphere in a oil while the oil drop spreads in water, because (A.F.=adhesive force C.F.=Cohesive force )

Millikan's Oil Drop experiment and Photoelectric effect

A large drop of oil whose density is less than that of water, floats up through a column of water assume that the oil an the water do not mix. The coefficient of viscosity of the oil is eta_(@) and that of water is eta_(W) the velocity of the drop will depend on
