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 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.
Do pure substances have a fixed boiling and melting point?
yes they have
How could you use the physical properties of melting and boiling point to identify a substance?
If you know the melting point and boiling point of a substance, you could look them up in a table to see what substances have those melting and boiling points. In practice, there are lots of other tests you'd probably want to do in addition, because in general there's no guarantee that an unknown substance is a single pure compound.
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 can the melting and boiling point help you identify it?
Each pure substance has its own unique melting and boiling point.

Adding impurities lowers the melting point and raises the boiling point.
Do pure substances have a fixed boiling and melting point?
yes they have
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.
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.

What are you physical properties that can help you identify a substance?
The traditional ones are melting point and boiling point.
What is mean by melting and boiling point?
Melting point & boiling point means the temp that things melt & boil. Water's freezing & melting point is 32 degrees Fahrenheit or 0 degrees Celsius. The boiling point of water is 100 degrees Celsius or 212 degrees Fahrenheit. Different liquids or substances have different melting, freezing, and boiling points.
How do the melting and boiling point determine the purity of the substance and identify them?
*usually* melting point is a good indicator of a substance's purity. The technique of melting point determination is used frequently in organic chemistry labs.
