That the human body is less dense then the water below them? Or, it shows that the oxygen in the blood and in the body/lungs is enough to keep us floating! :P

What is the relationship between human buoyancy and the ability to float in water?

Human buoyancy is the ability of a person to float in water. This is determined by the density of the human body compared to the density of water. If the body is less dense than water, it will float. If the body is more dense, it will sink. The relationship between human buoyancy and the ability to float in water is that the more buoyant a person is, the easier it is for them to float on the water's surface.


Does your body sink in water?

Whether or not your body sinks in water depends on your body's density. If your body is less dense than water, you will float; if your body is more dense, you will sink. Most people will float in water due to the density of the human body being slightly less than that of water.


Why does a human body float?

The uman body floats in water because its density is just under that of water.


Can coal float on water?

coal can float on water, because water's density is 1.0 g/cm3. and nothing is able to float on water unless it's density is less than water's density (; hope this helps you out! coal can float on water, because water's density is 1.0 g/cm3. and nothing is able to float on water unless it's density is less than water's density.


Would a human finger sink or float?

A human finger would generally float in water due to its density being lower than that of water. However, factors like oil or other substances on the finger could affect this.


Why is density needed to know whether a substance will float or sink in water?

It's actually pretty easy. If the density of the substance is higher than the density of water, the object will sink. If the density of the substance is lower than the density of water, the object will float. Be aware though that various substances may have dissolved into the water, thus changing its density. For example, seawater has a different density than fresh water.


What has more density water or human tissue?

Density is defined by how compact a particular substance is. In the case of the density of water verses the human body, your body is slightly less dense than water that is why humans can float.


If a matrial has a density of one will it float of sink in water?

If a material has a density of one, it will float in water. This is because the density of water is 1 g/cm³, so any material with a density equal to or less than that of water will float.


How much weight do lose when in water?

That depends on the person - a live human body is about the same density as water - some people sink, some float - just. In other words, you are about weightless in water.


Is it true that when the weight of an object is less than the density of water that object the object will float?

The weight does not determine if an object will float in water. If an object has a DENSITY that is more than the density of water then it will sink, if it's density is less than the density of water it will float.


Do people have density?

Yes but to be exact you would need a specific person. Most people have a density of slightly less than 1 because they float in water. If you do not float then your density is slightly greater than 1.


How are mass and volume related to the sinking and floating of an object?

An object will float - on water for example - if its density is less than the density of water. Density = mass / volume.An object will float - on water for example - if its density is less than the density of water.
