What will happen if you dropped an ice cube into liquid water at 85 celcius?
When you drop it in the water, the ice cube will splash into the water and be temporarily submerged. The depth of submersion depends on the force with which the ice cube strikes the water; but this is not really the same as the ice cube “sinking,” because it’s a result of the ice cube’s kinetic energy from falling, not a result of the ice cube’s own displacement in the liquid water. When water freezes into its solid state, it expands. This means that the water in a solid ice cube displaces a greater mass of liquid water it is placed into than it would it it were in its liquid form (e.g. water in a plastic bag, dropped into the water). An object which displaces a volume of water whose mass is greater than its own will float; one which displaces the same or less water will sink. The ice cube, which now takes up more volume than the original volume of liquid water from which it was created, displaces a greater volume of water for the same mass. It will, therefore, float in liquid water. T
