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.
What is the boiling point of matter?
When a substance is heated to its boiling point, the liquid begins to turn into a vapor. Thus, both phases of matter (liquid and vapor) will be present. Boiling point is the temperature at which atmospheric pressure equals the vapor pressure of the liquid. For this reason, the liquid is able to be released into the atmosphere as a gas.
What does the electron sea model of metallic bonds help you to explain?
Properties of metals as high boiling point, high melting point, malleability, ductility, electrical conductivity, thermal conductivity, lustre are explained by the theory of metallic bonds.
What is the effect of salt in boiling water?
It raises the boiling point of the water, so it takes longer for water to come to a boil. It raises the boiling point. Usually water boils at 100 degrees Celsius. Food tends to cook faster because it is boiled at a higher temperature.
Melting point of copper sulphate?
oh well I 'm finding the answer of this question and plus if some one answer me it will be great :) ------- The melting point of CuSO4.5H2O is 152 0C.
What are you physical properties that can help you identify a substance?
The traditional ones are melting point and boiling point.
What are two physical properties that can help you identify a substance?
The traditional ones are melting point and boiling point.
What info would help identify an element?
Atomic number, number of protons, melting point, boiling point, density..........
How can the boiling and the melting point be used to help identify substances?
intermolecular forces are hard to overcome...apex
How do melting points help scientists?
The melting point can help a scientist identify a substance.
Why can i use the melting point to help to identify a material?
Melting point is a specific property of materials.
How can information about the melting point and boiling point of matter help you know its states?
If the temperature is below the melting point, you know it is in the solid state. If the temperature is below the boiling point, and above the melting point, you know it is a liquid. If the temperature is above the boiling point, you know it is a gas, etc. (Note: melting point is the same as freezing point).
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 the two physical properties that can help you identify a substance?
Color, freezing point, or even texture if the substance is solid.
What is the significance of boiling point and melting point of a substance?
Melting points and boiling points are phyical constants which means specific compounds have specific melting/boiling points. Therefore you can identify a substance if you determine the mp/bp. Also you measure the purity of a mixture using melting point tests.
