The average human body has a density of 1.010 kg/litre
The density of pure water is exactly 1 kg/litre
The density of sea water is 1.025 kg/litre
So the average human is denser than fresh water but less dense than seawater.
There are significant differences in density between people, women tend to be less dense than men, muscular people tend to be more dense, fat people tend to be less dense. We can also reduce our density by breathing in deeply.
Incidentally dead bodies tend to float after a few days due to the build up of decomposition gases within the body reducing its density.

What else can I help you with?
Is chlorine less dense or more dense than water?
Chlorine gas is less dense than water, so it will float on top of water if the two are in contact.
Is oil less dense then water?
Kerosene and turpentine are less dense than engine oil. So is water and rubbing alcohol and other common liquids.
Is ice as dense as water?
Ice is less dense than water, that's why it floats.
Does lithium sink under water?
No, lithium is less dense than water, so it will float on the surface of water.
Which type of water is more dense cold salty water or warm less salty water?
Water is more dense the colder it becomes. It is also more dense the saltier it becomes.
Why boiled rice sinks in water and dead body floats?
Rice is more dense than water , while the human body is very less dense than water
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.
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.
Why does a body float in water?
A body floats in water because it is less dense than water.
Does dense water sink or rise in comparison to less dense water?
Dense water sinks in comparison to less dense water.
How can you determine whether a soild object is more dense or less dense than water?
You can put a uniform object into water.If it sinks density is higher than water,if floats lesser than water.If you can place anywhere in water,density is equal to water.
Most people can just about float in water what does this tell you about the density of the human body?
The fact that most people can float in water suggests that the density of the human body is very close to the density of water. This means that the human body is composed of tissues and fluids that have a similar density to water, allowing it to float rather than sink.
Is ice less dense or more dense than water?
no
Is water less or more dense than water?
Ice is less dense than water
What object is less dense than water?
A wooden block can be less dense than water.
Is a rubber ducky more dense then water?
no beacause a rubber duck floats and if an object floats in water, is is less dense than the water if it sinks it is more dense
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.
