100 degrees mate.
100 degrees Celsius is the boiling point for pure water at 1atm or sea level. The boiling point is useful in identifying chemical compounds. Chemical compounds have different boiling points that are specific to it' s chemical composition. If you know what the boiling point or melting point is you can also tell if your compound is pure, as any impurities will change these.

∙ 13y agoBecause they are unique to each pure substance.
Different substances usually have different melting points, so determining the melting point of a substance can narrow down the possibilities for the identity of the substance. Likewise different substances usually differ in their boiling points, so boiling point can narrow down the possible identities of a substance. Although two substances can have nearly identical melting points or have nearly identical boiling points, it is extremely rare for two different pure substances to have BOTH the same melting point AND the same boiling point, so taking the two together is usually enough to uniquely identify a substance, or at the very least narrow it down to a very small list.

∙ 14y agothese are the p[physical properties of the compound so if we know them so, when ever we handle them that is when ever we use them for the preparation of compounds so with the help of these physical properties we can further continue with the experiment
Wiki User
∙ 11y agoYou can compare them to tell one liquid from another. All solid substances melt at one temperature only.
Wiki User
∙ 14y agocause all pure substances have a fixed boiling and melting point unless impurities is added their boiling and melting will always remain the same.
Wiki User
∙ 12y agothese are pycical compounds so naturally when you use them we know what is in them so it is easier to use and we can go further into an experiment

How can the boiling and the melting point be used to help identify substances?
intermolecular forces are hard to overcome...apex
What Five characteristics or properties used to identify substances are?
Flexibility, Smell, Odor, Boiling Point, Melting Point, Texture, Color (there's seven for you)
Do pure substances have a fixed boiling and melting point?
yes they have
How is the melting point of asolid and boiling point of a liquidaffected when impurities are added to the substances?
Adding impurities lowers the melting point and raises the boiling point.
What property can be used to identify metal?
Specific heat, density, and melting/boiling point.

How could the identify of a compound be established by melting point?
Pure substances have very specific melting (and boiling) points. Assuming the substance is pure you could measure the melting point and compare it to a known database of melting points.
How do you identify solids at melting or boiling points?
Melting and boiling points are different for each compound or element.
What Five characteristics or properties used to identify substances are?
Flexibility, Smell, Odor, Boiling Point, Melting Point, Texture, Color (there's seven for you)
How can the melting and boiling point help you identify it?
Each pure substance has its own unique melting and boiling point.
Do pure substances have a fixed boiling and melting point?
yes they have
Explain why the boiling point and the melting point can be used to help identify substances-?
It's because substances have different boiling point and freezing point. By finding the exact boiling point and freezing point, you can identify a substance. Keep in mind that a material's melting point is the same as its freezing point. These are just different terms for the same thing, it just depends on whether energy is being removed from a substance (freezing) or if energy is being added to a substance (melting). The same thing also applies to the boiling/condensation point.
Why can the boiling point and the melting point be used to help identify a substance?
The boiling and melting points are almost unique to individual substances. If it should happen that two possible substances have the same melting point, they can still be identified by the method of mixed melting points. If substances A and B have the same melting point and you mix them, the mixture will melt belowthe tabulated temperature. Thus if you mix your unknown with a sample of what you think it is, if you are right it will still melt sharply at the expected temperature, but if you are wrong it will melt gradually and at a lower temperature.
How is the melting point of asolid and boiling point of a liquidaffected when impurities are added to the substances?
Adding impurities lowers the melting point and raises the boiling point.
What are the characteristic of pure substances?
The characteristics of pure substances are:fixed melting pointfixed boiling pointsfixed valencyfixed densitystability
What property can be used to identify metal?
Specific heat, density, and melting/boiling point.
Properties to identify substances are usually those that are what?
There are Physical Properties: Color, Density, Viscosity, Hardness, Lustre, Crystal Shape, Ductility, Cleavage, Solubility, Maleability, Boiling Point, Melting Point, and Conductivity!
