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 does boiling point and melting point find a substance?
The boiling point is the temperature at which a substance changes from a liquid to a gas, while the melting point is the temperature at which a substance changes from a solid to a liquid. These properties are unique to each substance and can be used to identify or characterize them.
How can the melting and boiling point help you identify it?
Melting and boiling points are physical properties unique to each substance, so knowing these values can help identify a substance. By comparing the observed melting and boiling points of an unknown substance to known values in a database, you can narrow down the possible identities of the substance. Substances with similar melting and boiling points are more likely to be the same compound.
Which is true of a melting point and a boiling point?
A melting point is the temperature at which a substance changes from a solid to a liquid state, while a boiling point is the temperature at which a substance changes from a liquid to a gas. Both melting and boiling points are characteristic physical properties of a substance and can be used to identify and classify materials.
Every substance has its own melting point and what?
Every substance has its own unique melting point and boiling point. The melting point is the temperature at which a solid substance changes into a liquid, while the boiling point is the temperature at which a liquid changes into a gas. These physical properties are characteristic of each substance and can be used to identify and distinguish between different materials.
A substance with a melting point of 50 degrees celsiusboiling point of 200 deg celsius?
The substance has a melting point of 50°C and a boiling point of 200°C. This information can help identify the substance by comparing it to known melting and boiling points of different substances. The melting point indicates the temperature at which the substance transitions from solid to liquid, while the boiling point is the temperature at which it transitions from liquid to gas.

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

The substance has a melting point of 50°C and a boiling point of 200°C. This information can help identify the substance by comparing it to known melting and boiling points of different substances. The melting point indicates the temperature at which the substance transitions from solid to liquid, while the boiling point is the temperature at which it transitions from liquid to gas.
How do you identify the change of state a substance is undergoing?
through it's boiling, melting, and freezing point.
How do the melting and boiling point determine the purity of the substance and identify them?
The melting and boiling points of a substance are characteristic physical properties that can be used to assess purity. A pure substance will have a sharp melting or boiling point, occurring at a specific temperature range. Impurities tend to disrupt the orderly arrangement of particles in the substance, leading to a broader or lower melting/boiling point compared to the pure form. By comparing the experimental melting or boiling point of a sample to the literature values for the pure substance, one can determine the level of purity.
What is the boiling melting and freezing point?
A boiling point is a point on the temperature scale at which a substance begins to boil. A melting point is a point on the temperature scale at which a substance freezes. Melting and boiling points are unique to different types of elements.
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.
Why can boiling points and freezing points be used to identify substance?
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.
