Detailed explanation-1: -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.

Detailed explanation-2: -In the question density of the object is equal to the density of liquid so it will float half-submerged in the liquid.

Detailed explanation-3: -If a liquid that is less dense than water is gently added to the surface of the water, it will float on the water. If a liquid that is more dense than water is added to the surface of the water, it will sink.

Detailed explanation-4: -Each substance has its own density, based upon the amount of mass per volume. Water has a density of one. Liquids and solids with a density greater than one will sink.

Detailed explanation-5: -Buoyancy pushes less dense objects to the surface of the liquid that they are in, allowing them to float.
