Question

Why does a block of plastic released under water
come up to the surface of water?​

Answer 1

Answer:

When it is more than gravity, it will bring it to the surface of water. Buoyancy force is more than gravity for materials with density smaller than water which holds for plastic and hence it comes up to the surface of water.
