What is bouyant?

Bouyancy is the ability of an object to float on or in a fluid. The force of buoyancy is equal to the weight of the displaced fluid and is determined by the volume and density of the object and the fluid in which it is submerged. If the object is less dense than the fluid, it will float; if it is more dense, it will sink. The buoyant force can be used to lift heavy objects in a process called buoyancy or to keep objects afloat, such as boats, ships, and planes. The concept of buoyancy was discovered by the Greek mathematician Archimedes in the 3rd century BC and is still widely used in modern engineering and physics.
