yes, very often its one of the best things to messure things with. Didn't you pay attention in 6th grade scinence?

If you had an unknown substance and were asked to identify it would you use the intensive or extensive properties of the substance?
Intensive properties are independent from the mass of an object: density, hardness, melting point.
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
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.
To find the density of and object you would use a graduated cylinder to find what characteristic t of the object?
Its volume.
What formula do you use to calculate the density of an object?
by calculate density by dividind the mass of space

Can you use weight to identify a type of material?
You cannot use just weight to identify a material.You can use density to identify materials.
What is the formula you use to calculate the density of an object?
Object's density = (its mass) divided by (its volume)
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.
Do you use the mass of an unknown material to identify it?
yes
What is taxonomic classification?
its use to identify unknown organisms
How can you use density to see if an object can float?
Usually, an object can float if it has a lower density than the liquid it is in.
How can you use math to predict if an object will float or sink?
If the object's density is greater than the density of the liquid in which it is placed, it will sink. If the density is less, it will float. You can use math to calculate the density, if you know an object's mass and volume. Density is defined as mass divided by volume.
How can density be used to identify an unknown substance?
Finding the volume and comparing it to the mass will give you the density, then it is simply a matter of looking up which materials have that density to find what it is. And that is how you can tell howthe density can be used
Do you use a dichotomous key to identify an unknown organism?
Yea (:
