An aluminium sphere is dipped into water. If Bi and Bii are the buoy

1.	An aluminium sphere is dipped into water. If Bi and Bii are the buoyancies in water at 0°C and 40°C respectively, then : (1) Bi < Bii(2) Bi > Bii(3) Bi = Bii(4) B, > or < B„ depending upon the radius of the sphere
Answer» Correct option (2) B_i > B_ii Explanation: Assuming volume of sphere is constant as density of water at 0°C is 999.9 kg/m³ and at 40°C 992.2 kg/m³ buoyant force is more when density is more.

Answer»

Correct option (2) B_i > B_ii

Explanation:

Assuming volume of sphere is constant as density of water at 0°C is 999.9 kg/m³ and at 40°C 992.2 kg/m³ buoyant force is more when density is more.
