The Attempt at a Solution
There can be two cases
1) The sphere might be a shell such that it floats on the water .When the temperature increases , even though density of water decreases , the force of buoyancy should remain same . Because force of buoyancy should be equal to the weight of the sphere at all times .
2) If it is a solid sphere , then it will sink and reach the bottom of the vessel. The volume of sphere will increase but the density of water decreases . So in the expression for force of buoyancy Vρg , V increases , but ρ decreases . So how can we conclusively say , which factor dominates ?
