Dead bodies can float instead of sinking due to the process of buoyancy. When a human body drowns, it typically fills with water, making it heavier than the surrounding water. However, the body’s overall buoyancy is influenced by various factors, such as the body’s composition and the gases within.
As a body decomposes, bacteria produce gases like methane and carbon dioxide. These gases accumulate in the body’s cavities and tissues, increasing its overall buoyancy. This can cause the body to rise to the water’s surface.
The human body is also made up of different tissues, each with varying densities. The combination of these factors, including the presence of air in the lungs, can affect the body’s ability to float. In some cases, the body may initially sink but resurface as decomposition progresses and gas accumulation occurs...See More
