Question

What is density and buoyancy​

Answer 1

Answer:

If an object's average density is less than that of the surrounding fluid, it will float. The reason is that the fluid, having a higher density, contains more mass and hence more weight in the same volume. The buoyant force, which equals the weight of the fluid displaced, is thus greater than the weight of the object.

Answer 2

Answer:

The quotient of Mass and Volume is Density.

Buoyancy is the phenomena in which a substance floats on water due to lesser density than the water.
