how come when you die in water you float but when your alive you sink?

Next time you're in the pool take a deep breath while wading towards the deeper end. Don 't paddle. You may not stay upright but you will stay at the surface. Now as you're floating there let all that air out of your lungs, you'll start to sink...Just a little exercise...But after a body dies and decomposes in the ocean, gases are made in the body due to decomposition process (such as carbon dioxide, methane and others) these gases fill the corpse causing a "bloating" and the body will then come to the surface. Thats why gangsters used to make "concrete shoes"...

perhaps u dont eat enough fiber, so your intestines arent as able to compact your feces as tightly, resulting in less dense feces which float in water. Eat more fiber, and u should have the brown submarines in the toilet bowl. lol

Having been in the stuff while my more experienced friends stood around and laughed, I can tell you -\n\nYou won't drown.  Its just like water, only thicker.  It doesn't "suck you down".  Stay calm and swim out slow motion.

Both are floating because of differences in bouyance and density.\n\nThe hot air balloon floats because it is less dense than air making it bouyant. It will consequently rise into the air until the weight of the air it displaces is equal (density) is equal to that of the surrounding atmosphere, which is why balloons do not go flying off into space.\n\nA scuba diver has the same problem, but in reverse. As he goes deeper, the density of the water is increasing and pushes him or her back. Therefore, divers tend to sink to a specific depth unless they can increase their density. This is usually accomplished by bringing additional weight.

Maybe it has something to do with the actions you're making.  When you're timing yourself out of water, you're just sitting there right?  But when your under water, you're treding or moving in some sort?  Try timing yourself when your walking around the house or jumping up and down....the blood takes in more oxygen(which means you need more) when its pumping faster.  Just an idea!

When you are live and kicking you are supposed to be a conscious person but who can become unconscious at times but once the LIFE goes out and you are declared DEAD you are no more conscious that is you become permanently unconscious!!!There is on in between stage called COMA(Vegetable) stage where your breathing goes on and you are kept alive by life saving devices but you do not regain your consciousness any more and the moment the life saving support is with drawn you become NON ALIVE or DEAD .\nThere is yet one more different stage where you are conscious but in a deep coma like meditation stage and alive too but you do come back to normalcy subsequently at your own will but may be oblivious of what ever happened around you or to your body even.You may even might have gone out of your body and returned back.Hindu philosophy says that one may leave the body and enter another body and then return back to old body.

Your lungs will do the same job as the beach ball.  If you can relax and keep air in your lungs, you will float.  Try in shallow water, take a good breath, relax and lay back.  You will be fine.

Most people who drown do not have water in the lungs due to a bronchospasm that shuts off the windpipe. He would not have water in the stomach either, because swallowing requires peristalsis through the espophogus. \n\nIam sorry for your loss.

Every body that is in a fluid, or it is floating on the surface, or is sunk to the bottom loses an equal ammount of weight as the weight of the displaced fluid by the volume of the body.\n\nThe force that makes body's float or makes them lighter in a fluid (for ex. water) is called Archimed's force or Archimed's principle.\nIf this force is grater then the weight of the body (G=m*g) then the body floats on the surface.\n\nArchimed's force is greater if the density of the fluid is bigger. Oil has the density of 900 g/cm3 and water has the density of 1000 g/cm3. Because the reason why the objects are floating in oil and in water is of same nature, floating on oil is similar to floating on water.\nBut water has a bigger push force then oil.

Objects float because the density of the object is less than the density of the liquid. If you increase the density of water by dissolving something, such as sugar or salt, in it and create a situation where the density of the water exceeds the density of the egg, the egg will float.

We're accustomed to walking around in air. Water weighs more than air, so we feel lighter in it.

Keep in mind that all animals and humans die the same way.  The final result is brain asphyxiation or suffocation of the brain.  As long as a continued supply of blood is being transported to the brain you will remain "alive".   So, no matter how much trauma has effected your body, if your brain is still receiving a fresh blood supply you are still "alive".

The object must be less dense than the fluid to float, and more dense to sink.  If it is exactly equal density, then it can be suspended.

The reason you floated better in the ocean is because the density of salt water is different than regular water. \n\nThink about keeping your hips high. If you're on your back, press the back of your neck/head to the bottom. If you're on your stomach, it's very natural for your legs to sink slightly. Just keep your hips up!

Because of buoyant force acting against our weight. The amount of the bouyancy is decided by the Archimedes principle according to which the force acting on us in the upward direction is determined by the amount of water displaced by us which indeed is equal in volume to the volume of the submerged part of our body. \n\nThe buoyant force acts upward and balances our weight so that the net force acting on our body becomes 0 and we feel weightlessness.

Dead things often end up on their backs because that is the equilibrium position with their center of gravity lowest to the ground. Dead fish float upside down because that places their center of gravity nearest the surface. Either way, the energy of the system is minimized. SUVs easily tip over for the same reason - too high a center of gravity

Yes.  Technically, you only need to suck water into your lungs to drown.  Since doing so usually causes death almost instantly, very few people survive the ordeal.  \n\nThat said, though, if someone is able to force the water out of your lungs and revive you, then you drowned and lived to talk about it.
