If an object sinks in water its density is less than that of water true or false?

Well, a dead body may sink in water then float, because the bodily gases will later bring the body back up to the surface after a little bit of decomposition.
Other than dead bodies, no solid object will sink then float in water.
Submarines might also fit the bill, if your not sticky about the methods.

It really is complicated. Some objects float mainly because of their shape; you could float a glass bowl on water if it has a stable enough shape, but a sphere of glass with the same mass as the bowl would obviously sink. Many of the materials in an ocean liner would sink, including the materials that make up the hull and basic inner structure, if they were formed into spheres.
But not all substances would sink even if formed into solid spheres. Such an object will sink in water if its density is greater than the density (specific gravity) of the water. It will float if it is less dense than the water.

Does copper sink in water?
Copper does not sink in water.. An object with higher density than water sinks while an object with lower density than water floats..
Why do some things float and why do other things sink?
The object which have more density than water it sinks and which have lower density than water it floats.
Does the shape of an object affect whether it sinks or floats?
No, every object has a fixed density. if the density is less than water it will float. If not, it wont. Hope this answers your question!
How does the temperature of water affect the speed at which an object sinks?
Yes. As water is heated above 4oC it expands. With this change in volume comes a change in density. Less density means less bouyant force on the object in the water.
When an object sinks its denser than water?
Yes. Water has density of 1 g/mL. If an obct has a density lower than that, it will sink. some objects, however, will float under water.
When you compare the density of water or air with another object how can you tell which has the lower or higher density?
-- If the object floats in water, then its density is less than the density of water. -- If the object sinks in water, then its density is more than the density of water. -- If the object floats in air, then its density is less than the density of air. -- If the object sinks in air, then its density is less than the density of air.
What happens if an object of higher density is placed in water?
Higher than what ?? If the object's density is higher than the density of water, then the object sinks in the water.
How do you know an object has a density greater than water?
If an object placed in water sinks - then it has a density greater than water.
If an object sinks in water what is its dencity?
More than the density of water.
What is density in everyday terms?
Density is how well an object would float when put into water. Water has a density of 1, so if the object floats, it's density is less then 1. If the object sinks, then it's density is greater then 1.
What is an object with a greater density than water will float in water is it true or false?
False
Why do some objects float and others sink?
Whether an object floats or sinks is a function of its relative density, to the medium in which it is placed. If the object is less dense, it floats, If it is more dense, it sinks. Density = Mass per unit Volume
What causes something to sink or float?
What causes it to sink or float is the density. The density of water is 1.0. If the object's density is more 1.0 then it sinks, but if the object's density is less then 1.0 then the object will float.
When will an object an object sink?
an objects sinks when its density is more than that of water...... that means when the density of the material is more than 1g/cm3
Does a piece of rubber sinks in salt water?
This depends on the density of this object; if the density is over 1 g/cm3 the piece sink in water.
How do things sink and float?
it depends on the density of the object and the density of the liquid that it's in. if the density of the object is greater than the density of the liquid, then the object will sink. if the density of the object is lesser than the density of the liquid, the object will float.
Does copper sink in water?
Copper does not sink in water.. An object with higher density than water sinks while an object with lower density than water floats..
