Question

why does the body of a dead person float on water?​

Answer 1

Answer:

our body is made up of 75% water, when the person dead then their body dehydrated, that is the cause which makes the person body floats

Answer 2

Answer:

The bodies of the drowned sometimes surface on their own, but this depends on the qualities of the water. The putrefaction of flesh produces gases, primarily in the chest and gut, that inflate a corpse like a balloon. In warm, shallow water, decomposition works quickly, surfacing a corpse within two or three days.
