Question

When we are alive, we are submerged in water. But when we die, why does our body float on top of water? ​

Answer 1

Explanation:

Once the body is submerged under the water, then the body stays under the water until the bacteria in the gut and the cavity in the chest can produce enough gases such as methane, hydrogen sulfide, and carbon dioxide in order to float on the surface of the water like a balloon.
