Why does every substance have a characteristic density?
Density is a physical property of a substance that is determined by the mass of its particles and the volume they occupy. Each substance has a unique arrangement of atoms or molecules, which affects the packing and spacing of its particles. This unique arrangement results in each substance having a characteristic density.
The amount of mass for each milliliter of a substance determines the substances?
The amount of mass per milliliter of a substance is known as density. Density is a physical property unique to each material and can help identify the substance based on comparison with known values. By measuring the density of a substance and comparing it to a reference table, scientists can determine the identity of the substance.
Is the density of a substance a physical property of the substance?
Density is classified as a physical property because the density of a substance can change when the substance changes state. Example: When water evaporates it is a physical change and the density changes. A chemical property is a property that describes its ability to react chemically with other substances and THEREFORE density is not a chemical property.YES.
Why are a substance's physical properties a reliable means to identify it?
A substance's physical properties, such as color, density, melting point, and solubility, are determined by the arrangement of its atoms and molecules. These properties are unique to each substance and do not change regardless of the amount or form of the substance present. Therefore, by comparing the physical properties of an unknown substance to those of known substances, we can reliably identify it.
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 is density of a substance like a human fingerprint?
The density of a substance is a unique physical property that remains constant, just like a human fingerprint is unique to each individual. Density is a measure of how tightly packed the molecules in a substance are, and this characteristic can help identify the substance. Just as fingerprints are used for identification purposes, density can be used to distinguish different substances based on their unique values.

Is The density of a substance is the same for all samples of the substance?
Not necessarily. The temperature of the samples would have to be the same. It can also vary with how pure the substance is.
Why are mass and volume not characteristic properties but the density of a material is?
Mass and volume can vary depending on the size or amount of a substance, while density remains constant for a specific material. Density is a characteristic property because it is unique to each substance and helps identify the substance regardless of its mass or volume.
Does every substance have its own density?
Yes, every substance has its own unique density, which is defined as mass per unit volume. The density of a substance depends on its composition and how closely its particles are packed together.
What are two reasons why density is a useful property for identifying substances?
Density is specific for each substance. Also the measurement is generally simple.
How do you calculate two densities in order to find the density of the combined substances or objects?
To get the average density of the combination, you need to divide the total mass by the total volume. Just knowing the density of each substance you combine is thus not enough; you also need to know how much quantity of each substance is involved.To get the average density of the combination, you need to divide the total mass by the total volume.

What kind of changes in substance are always physical changes?
each substance has a density that differ from the densities of other substance.
How do you calculate the relative density of a substance?
To calculate the relative density of a substance, you divide the density of the substance by the density of water. The formula is: Relative Density Density of Substance / Density of Water. The relative density is a measure of how dense a substance is compared to water.
How can density be used to determine the identity of a substancce?
Density can be used to determine the identity of a substance by comparing the density of the unknown substance to the known densities of different substances. Each substance has a characteristic density, so if the density of the unknown substance matches that of a known substance, it can help identify the unknown substance.
