Objects like Stone and metals have density greater than the density of water, therefore they sink in water.
piece of paper didn't sank they float
paper floats because it is less dense than water, so it floats to the surface. However, if it gets completely soaked then it will become more dense than water and sink
key is sanking
Keys are harder and more solid, so they sink.” This is a simplified way to say that objects with a lower density have more space between their molecules, like the Nerf bullets. Keys, on the other hand, are made of dense metal. The molecules in metals are tightly packed.
cotton ball is floating in water
Cotton balls only float while is air trapped between the fibres. ... When all the air has been replaced by water, the cotton ball sinks. Cotton balls sink faster in hot or soapy water because both will wet the cotton fibres and replace the air trapped between them much faster than pure cold water.
wood can float
wood is less dense than water. Since wood is less dense than water, wood floats in water, no matter how big or small the piece of wood is.
