Lungs do not sink in water mainly because of their composition, which is made up of tissues, air sacs, and blood vessels that have a lower density than water. This lower density allows the lungs to float rather than sink in a liquid substance like water.
Lung tissue is denser than water and will sink when placed in it.
A drowned child would initially float due to the air trapped in their lungs and clothing. However, as the body decomposes and water fills the lungs, the body would eventually sink.
Lung tissue would typically sink in water because it is denser than water. The air sacs in the lung would collapse and the tissue would be more solid, leading to sinking rather than floating.
The human reflex is to breathe in air when the lungs need it. So the lungs dont burst from not getting air, the person instinctively opens their mouth for air and swallows all the water, which then fills their lungs with water. Once all these gasses have escaped from the body its average density is higher than water and so the body sinks. Interstingly dolphins are the only mammals that do not have the reflex memtntion above and so when they are trapped in a net under the water they hold their breath and suffocait themselves.
Rocks sink because they are denser than water, causing them to displace less water and therefore sink. Metal objects sink due to their high density, which makes them heavier than water and causes them to sink. Sunken ships sink because they take on water, increasing their overall weight and causing them to sink below the water's surface.

Whales alter their bouyancy depending upon the amount of air that they have in their lungs.

Because you dont breath when you drink water
Yes. I put my goldfish in water strait out of the sink. We have a well so I dont know about city water, but I know that you can put well water strait out of the sink. Hope this helps.
No, galena does not float in water because it has a higher density than water. This means that galena will sink when placed in water.
Absolutely. Everything that breathes air has lungs.
no they dont float like normal people
The lungs can't have water in them. Just to keep them moist. But if they did have, i dont know, 86 percent water, just for say, you would like so called "drown" on land I guess.
In fresh water a human is more dense than the water around him or her causing them to sink slowly. In salt lake the water is more dense than the human because of the fact that it has salt in it causing the human to float. Also have you ever noticed that if you fill your lungs with air the in fresh water you will float, but if you fully deflate your lungs you will sink? pretty cool huh?
