Question

When a paper is put in a bucket of water, it floats. This is because density of paper is less than the density of water. However, if it is forced to the bottom, it does not return to the top. If the paper has less density, shouldn't it just float back to the top? Does this mean the paper is just floating because of surface tension and it has nothing to do with density and buoyancy?

Answer 1

After the paper gets wet then the weight of wet paper is more than dry paper... Simply because paper absorbs water. That's the reason hope u like it
