Is density a good way to identify a substance?
Yes, it is possible. To identify an object using its density you need only a few things: an accurate scale to find the mass of the object; a graduated cylinder large enough to accommodate whatever object you have; the object itself; and a liquid. Any liquid can be used for this, however, if the object floats then the calculation becomes slightly more complicated. I use water. First weigh the object, then immerse it in the liquid. Note how much water is displaced. Divide the mass of the object by the volume of the liquid and you'll find the density. Then compare that density to the list of known densities to identify the object. Pretty simple! physical and chemical properties can be uesed to identify substance. I used: http://www.ehow.com/how-does_5187289_density-used-identify-substances.html Ans: Not sure you can actually identify the substance from its density alone: you would have to know its state too. For example, water in gaseous form would be an entirely different density to water in solid form wouldn't it? So no, you cannot identify a substance from its density, without other information. The best way to identify a substance is often through spectroscopy, in which the radiation either absorbed or given off from a chemical can determine which substances are present. This is what happens for the sun.
How can knowing density of the object help you identify what the object is made of?
Well, I think it helps you identify if the objects in the object are dense or not. Just sometimes things make things denser or thinner. I hope this helps and it's not TOO confusing!

What factors determine how heavy an object can be and still float?
An object will float if it has less density than the density of the liquid.An object will float if it has less density than the density of the liquid.An object will float if it has less density than the density of the liquid.An object will float if it has less density than the density of the liquid.
An object will float if?
density of the object < density of the fluid
Why can you use density to identify an element?
density and be used to identify an element because of the types of molecules. Use D = M v
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.
How do you use density to identify an unknown object?
yes, very often its one of the best things to messure things with. Didn't you pay attention in 6th grade scinence?
How can density be use to determine whether an object will float or sink in a fluid?
When you have the density of both the object and the fluid, just see which has a higher density. If the object has a higher density than the fluid, the object will sink. If the object has a lower density than the fluid, the object will float.
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 physical properties are used to calculate the density of an object?
Mass and Volume are physical properties that can bed measured. By themselves, neither can bed used to identify unknown objects or substances. However, if you have measured the mass and the volume of an object, you can calculate its density.
How do you figure out density?
To find the density of an object, you have to divide the mass of the object by the volume of the object.
