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.

Is chalk less dense than salty water?
No, it is more dense. If it were less dense it would float.
Is chlorine less dense or more dense than water?
more dense
Is a ice cube more or less dense than liquid water?
Ice cubes are less dense than liquid water, which is why they float.
Is ice as dense as water?
Ice is less dense than water, that's why it floats.
Is zinc less or more dense than water?
zinc is more dense than water
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
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.
Most people can just about float in water what does this tell you about the density of the human body?
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
Why does a body float in water?
A body floats in water because it is less dense than 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.
Is ice less dense or more dense than water?
no
Is water less or more dense than water?
Ice is less dense than water
Why does a Human body floats after death?
After a human body dies, it begins to decompose and this causes gases to accumulate which will cause the body to float, temporarily.
What object is less dense than water?
A wooden block can be less dense than water.
How can you determine whether solid object is more dense or less dense than water?
If more dense, it will sink when put into water; if less dense it floats.
Can you make oil less dense than water?
Oil IS already less dense than water.
Is liquid water less dense then Ice?
No. Ice is less dense than water. Because ice is less dense it displaces less water and floats. Water is most dense at 4o C. any change in temperature, either up or down, lowers the density.
