An aluminium sphe A. will increase

B. will decrease

C. will remain constant

D. may increase or decrease depending on the radius of the sphere.

Answer :

Buoyancy is nothing but the force which is


responsible for the body to flow.



If the temperature is increased, then the density of the water will decrease, and the aluminium ball will start expanding leading to increase in its volume which leads to decrease in the volume displaced by the aluminium sphere. Therefore, the buoyancy will decrease.
