This happens because of density difference. Density, the mass of a material substance per unit volume. Density can be expressed as d = M/V, where d is the density, M is the mass, and V is the volume. The most common way to describe density is in grams per cubic centimeter.
Water, for instance, has a density of 1 gram per cubic centimeter, while the Earth has a density of 5.51 gram per cubic centimeter. Density can also be expressed in metric kilograms per second (or SI units) as kilograms per cubic meter.
Because of its weak intermolecular force of attraction, ice has a lower density than water, which reaches its maximum density at 4 degrees Celsius. Water is heavier than ice because it has a higher density. As a result, ice floats on water's surface.
The more is the density of material it will get sink in water.
The lesser is the density of material it will float in water.
