What else can I help you with?
If you had an unknown substance and were asked to identify it would you use the intensive or extensive properties of the substance?
To identify an unknown substance, you would typically use its intensive properties. Intensive properties, such as density, boiling point, and specific heat, are independent of the amount of substance present and are useful for identifying specific materials.
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.
What experiments do scientists use density for?
Scientists use density measurements to determine the composition of a substance, identify unknown substances, study the buoyancy of objects in fluids, and analyze the purity of a material. Density can also be used to investigate phase changes and conduct experiments in geology, chemistry, and physics.
Why can you use density to identify an element?
Density is a physical property that is unique to each element and can be used to identify it. By measuring the density of a substance and comparing it to known values in the periodic table, you can determine the most likely element present.
How would you calculate the density of an object?
Density is calculated by dividing the mass of an object by its volume. The formula for density is: Density = Mass / Volume. Make sure to use units that are consistent, such as grams for mass and cubic centimeters for volume, to get the correct density value.
How do you you find the density of an object by comparing it to another known density of a solution?
If your experiment shows that your unknown material has twice the density of your known material, you can simply look up the density of the control material and double it (or multiply by whatever the ratio is). This will give you the density of the unknown and you can attempt to identify it by looking for this number in a density table.

How can you find out weight of an unknown object by using standard masses by scale or by ruler?
To find the weight of an unknown object using standard masses and a scale, you can use a balance scale. Place the unknown object on one side and add standard masses to the other side until the balance is achieved. The sum of the standard masses used will be equal to the weight of the unknown object. To find the weight of an unknown object using a ruler, you can use the concept of density. Measure the dimensions of the object to calculate its volume, then weigh the object to find its mass. Using the formula density = mass/volume, you can determine the weight of the object by multiplying its volume by the density of the material it's made of.

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
How is density calculated and how do scientists use it?
Density is calculated by dividing an object's mass by its volume. It is used by scientists to identify and classify materials, as well as to predict how objects will behave in different environments based on their density. Scientists also use density to study properties of materials and analyze their composition.
What is the formula you use to calculate the density of an object?
Object's density = (its mass) divided by (its volume)
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 experiments do scientists use density for?
Scientists use density measurements to determine the composition of a substance, identify unknown substances, study the buoyancy of objects in fluids, and analyze the purity of a material. Density can also be used to investigate phase changes and conduct experiments in geology, chemistry, and physics.
What is taxonomic classification?
its use to identify unknown organisms
Do you use the mass of an unknown material to identify it?
yes
Can you use density of an object to predict whether it will float or sink in water?
Yes, you can use density to predict whether an object will float or sink in water. If the density of an object is less than the density of water (1 g/cm³), it will float. If the density of an object is greater than the density of water, it will sink.
