if we placed a piece of paper in the bowl of water it will float later on sink and no displaced waater come out. this means that the Archimede's principle does not stastisfy in this situtation

Expert Answer:

Floating of paper piece is based on Archimedes’ principle, says that the buoyant force is equal to the weight of liquid displaced by the piece of paper. Hence, when a paper piece is floating, the weight of water displaced by the submerged part of the paper is equal to the weight of the paper. Although, paper piece is less dense than water, so it floats to the surface and water displaced by it, is negligible. When it gets completely soaked then it will become denser than the water and eventually it sink.
