Question

A stone suspended from a spring balance is first weighed in water and then in salt solution of density 1.2 gram per cubic centimeters. In which case the spring balance will register less weight and why?

Answer 1

Explanation:

this is because the addition of salt increases the density of the water

buoyancy depends on the density of the liquid

more density=more buoyancy

Answer 2

Explanation:

• The stone that is suspended from the spring balance will be less when it is put inside the salt solution because of the change in density of the solution.
• The solution of salt has a higher degree of density than a simple water because of which the buoyancy of salt solution increases does pushing the stone outward which makes the stone less heavier, then it was before when it is put in water.
