Question

cotton is a solid yet it floats over water. why....and 0lz dont copy it from google as i have already searched it ...and i cant undersand it...so plz try to explain it on your own ​

Answer 1

The density of a cotton ball is lesser than the density of water, thus it can float on water.

Answer 2

Answer:

See, Anything that has a density more than that of water would sink if kept on the surface of water.

When you place a cotton Ball on water ,It does not sink as its pores accomodate air . Therby reducing its density.

in short Density of Cotton ball is less than the density of water. lowering of density is due to trapping of air by its pores .

Hope this helps.
