Identifying Material Based on Density

In summary, the conversation is about a person's sister who is conducting an experiment to identify different materials based on their densities. The person is asking for links to tables with densities of various woods and metals, as the values their sister found do not match with the table they have. They also mention the values for each material, including a link to a conversion table for US/British measurements.

My sister has an experiment where she's found the densities of 3 woods and 2 metals, and is asked to identify the materials based on these calculations. Does anyone know of any good links to tables that has various woods and metals and their densities. I have a table of properties of various woods, but the densities she found don't exactly show up on the table. Thanks. In case you happen to know off-hand, or if it helps finding an appropriate table, the values are:

Wood A : 0.646 g/cm³
Wood B : 0.178 g/cm³
Wood C : 0.634 g/cm³
Light Metal : 2.95 g/cm³
Dark Metal : 8.48333... g/cm³

But you have to convert to the US/Brit measurement (imperial).

Hope this helps

There are many resources available online that provide tables of densities for various materials, including woods and metals. One useful source is the National Institute of Standards and Technology (NIST) website, which has a searchable database of material properties. Another option is the Engineering Toolbox website, which has a comprehensive list of densities for common materials, including woods and metals.

In terms of your sister's experiment, it is important to note that the densities of materials can vary depending on factors such as moisture content and temperature. It may be helpful to compare the values she obtained to a range of densities for each material rather than relying on a single value. Additionally, it may be useful to consider other properties of the materials, such as color and texture, to further aid in their identification.

I hope these resources are helpful in identifying the materials your sister tested. Good luck with the experiment!
 

What is density?

Density is a measure of how much mass is contained in a given volume of a substance. It is often expressed in units of grams per cubic centimeter (g/cm3).

Why is identifying material based on density important?

Identifying a material's density can provide valuable information about its composition and properties. It can also help distinguish between similar substances and aid in quality control and product testing.

How do you calculate density?

Density is calculated by dividing the mass of a substance by its volume. The formula is: density = mass / volume

Why do different materials have different densities?

Density is determined by the mass and volume of a substance. Therefore, materials with different compositions and structures will have different densities. For example, a material with a more compact molecular structure will have a higher density than a material with a less compact structure.

What are some common methods for measuring density?

Some common methods for measuring density include using a balance or scale to measure mass and a graduated cylinder or other measuring device to measure volume. Other techniques, such as x-ray densitometry and displacement methods, can also be used.
