Question

Dear All, 

Can help me with this question ? 

Thanks 

 

Answer

Issac can pour sea salt into the tank until the plastic bag floats to the surface. By pouring the sea salt into the tank, the increased mass per volume will result in an increase in the density of the water in the tank. When sea salt is added to the point where the water becomes denser than the plastic bag, the plastic bag will float to the surface.
