An Aluminium Sphere

Classical Mechanics Level 2

An aluminum sphere is dipped in water at 1 0 o C 10^{o} C . If the temperature is increased, the buoyant force:

will increase will remain the same will decrease may increase or decrease depending upon the radius of sphere

After 4°C , with increase in temperature, the density decreases. Sice buoyant force=Vdg, the buoyant force will decrease

But the sphere will expand too, thus increasing the volume.

I think that increase in volume will not be significant by decrease in density will be significant

The volume of the aluminum sphere is going to change negligibly.

@The Empress Of Physics , Mam, this is a good argument, can you please provide me a solution to @Akshat Sharda's argument, and check whether my solution to the argument is right?
