What is an example of Flotation?

Hint: Flotation is explained as the phenomenon that is related to the concept of relative densities of objects. The floating of an object depends on the density of the object and the liquid. We can also understand the floating concepts and related examples with the help of relative densities.




Complete answer:
Whether the object will float or sink in the liquid will depend upon their relative densities. When the object has a lower relative density than the liquid then the object will float in the liquid else it will sink.
So, if a body has a density that is less than the density of water then it will float. By using this concept, we can find many examples like the leaf of a plant floating on the water due to the density of the leaf being less than the density of the water. On the other hand, if a stone thrown in water sinks due to the density of stone being more than the density of water.
Similarly, paper, kites, gas-filled balloons, hot air balloons, dust, birds, flies, airplanes, satellites, soap bubbles, feathers, and dried leaves will all float in the air.




Note: An object may also float in a liquid even if the density of that object is more than the liquid. This happens only if the liquid displaced by the object will be greater than the weight of the object itself. This will create more buoyant force than the weight of an object and thus will help the body to float.
