In what conditions does a body that is heavier than water float in water?
Ok…to answer ur question i can recall of two answers….
Take a bloating paper and keep a small needle on top of it. Fill a small jar with water and keep paper on the top surface of water. Avoid any fan in the area or vibrations or movement of jar. After some time paper will sink after absorbing water but needle will keep on floating untill the water surface is disturbed. This is due to surface tension. Needle is heavier than water but will float.
Second condition is when u see a human swim. Even if overall weight of person is higher that water of his equivalent volume he floats. The reason is because he displaces water by his hands and legs. The weight of displaced water is resposnsible for his floating. Similarly other floating things like fishes and all.

Q: In what conditions does a body heavier than water float in water?
Two conditions. Either….
The body has a large volume, so that even though the material might be something “heavier” (denser) than water like steel or concrete, the overall structure is less dense than water and so floats. This is the case with ships, for example.
The body is small enough, overall, that it cannot break the water’s surface tension.
Make it hollow.
A lean human would probably sink if his/her lungs were emptied of air but will float with full lungs.
Below is a concrete boat. Concrete is often used in block form as an anchor. But this boat is, naturally, hollowed out in the middle and so floats quite well.
Another good way for things denser than water to not sink is to wait until the water freezes. Here is a person walking on water.
When it displaces an equal mass of water.
Hence, steel, which is inarguably denser than water, can be made to float on water.
How does a ship float on water?
Short answer: BUOYANCY
Any object will either float or sink in water depending on its density. If it's more dense than water, it will usually sink; if it's less dense, it will float. It doesn't matter how big or small the object is: a small pebble will sink, while a large piece of plastic may float. The basic rule is that an object will sink if it weighs more than the same volume of water.
A ship does not actually 'float' - but it partly floats and partly sinks according to its own weight and how much weight it carries; the more the weight, the lower it sinks in the water. You may remember the "
Can anyone float in water for hours without moving their body?
Hey guys, I found it urgent to inform readers why a person who had inhaled a large breath of air will float more easily than he who's just exhaled. This is solely due to the volume and not a result of the air (not oxygen, persay, for air is approx 78% nitrogen, 10% oxygen and 2% argon, carbon and various regionally dependent gases and/or vaporized liquids.) Most of you have heard the term buoyant force. The buoyant force is equivalent to the density of the [surrounding] fluid multiplied by the force of gravity and the volume of the object known as the volume of liquid displaced once on object'
How does a body float on water even when the density of human body is more than that of water?
Density of water is 1gm/cc and density of human body is very close to it. This will however change depending on the amount of water intake or air inhaled. With good amount of air in the lungs it is very close to water density and hence it can float.
If you have ever noticed a swimmer floating on water most of the body will be under water only a small portion will be breaking the surface. This clearly shows
