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.

The melting point and boiling point of a pure substance are very specific numbers; knowing these allows you to narrow down the possible identity of the substance.

What physical property dose not identify a substance?
boiling point --------- Boiling point is a specific characteristic of a substance or element; the mechanical strength, the viscosity, the electrical resistivity are more difficult to be used for a sure identification of a substance.
How can physical properties be used to identify substance?
Every substance has certain properties that show things about them, such as odor, taste, malleability, hardness, color, state at room temperature, and melting/boiling point. If you know the color of a substance, it is far easier to determine what that substance is, and if you know the color and the boiling point, your choices are limited even further. Using the physical properties of a substance, you can identify the substance based off of its unique properties or combinations of properties.
How to identify substances using their properties?
The answer is Physical and Chemical properties
What physical property identify a substance?
There are many varying physical properties used to identify a pure substance. Some of the most prevalent physical properties are color, odor, density, melting and freezing points and solubility.
What are the two physical properties that can help you identify a substance?
Color, freezing point, or even texture if the substance is solid.

What are you physical properties that can help you identify a substance?
The traditional ones are melting point and boiling point.

Are melting and boiling point physical properties of a substance?
Melting and boiling points are physical properties of materials.

What is physical propety?
Physical property is a property that a substance has which can be measured. For instance, some properties are melting points or boiling points.
Is the boiling point of a substance a physicsl property?
No, the boiling point is a physical property because the compound or substance is not changing chemically (only physically from a liquid to a gas). The boiling point is considered the temperature at which the vapor pressure of the liquid equals the atmospheric pressure surrounding the liquid. All of these are physical properties, making the boiling point a physical property too.
How can chemical and physical properties help identify substances?
Certain combinations of physical properties are unique, so if you have a substance that needs identifying, you can measure its properties and use the results to figure out what you have been measuring. For example, if you have a transparent liquid with a density of 1 g/ml, a refractive index of 1.3330, chances are you're looking at water.
What type of property cannot be observed without changing composition of a substance?
a physical property a chemical property; physical properties are properties such as freezing/melting/boiling points
