If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float. Density is a characteristic property of a substance and doesn’t depend on the amount of substance.If the density of the object immersed in the liquid is more than the density of the liquid itself, the object will sink in the liquid. On the other hand, if the density of the object immersed in the liquid is less than the density of the liquid itself, the object will float on the liquid.
