A small quantity of liquid which does not mix with water sinks to the bottom at 20 degreeC ,the densities of the liquid and water at the temperature being 1021 and 998kg m^-3,respectively.To what temperature must the mixture be uniformly heated in order that the liquid forms globules which just float on water?The cubical expansivity of liquid and water over the temperature ranges are 85X10^-5K^-1 and 45X10^-5K^-1
