How can melting point and boiling point determination be used in identifying and or characterizing unknown compounds?
compounds are identified because each compound have characteristically different melting and boiling points.
How you can determine the melting point of a compound using capillary tubes and a digital melting point apparatus that need to be calibrated each time of use?
Melting points are ranges usually. It starts when the first crystal of the substance being tested melts and ends when the last crystal melts. Therefore the smallest sample possible and the slowest rate of heating will give the most accurate melting point.
How are melting point and solidification point related to each other?
The melting point and solidification point of a substance are the same. They are the point of transition between solid and liquid. This temperature is the melting point if the substance starts out solid and is the solidification point if the substance starts out liquid.
What point does it become a liquid?
The boiling point of a substance is the point at which that substance will change between being a gas and a liquid. For example, the boiling point of water is 100oC, so water vapour will change to water at this temperature. The boiling point of Methane is -161oC, so any temperature above this, Methane will be in gas form.
What is a crystalline solids melting point?
Name this crystalline solid; each compound and material have a different melting point.

What is the approximate value of the normal melting point?
Each material has a specific melting point.
Why should each sample be tightly packet in melting poin tinto the capillary tube prior to heating?
It is Important to pack tightly in order to prevent the entrance of air into the capillary tube.
What is the melting point of toner?
The melting point of toner is approx. 120 oC; the value is specific or each manufacturer.
What is melting point of cooking oil?
Each cooking oil has a different melting point. Search data for a specified oil.
How can the melting and boiling point help you identify it?
Each pure substance has its own unique melting and boiling point.
How are melting point and solidification point related to each other?
The melting point and solidification point of a substance are the same. They are the point of transition between solid and liquid. This temperature is the melting point if the substance starts out solid and is the solidification point if the substance starts out liquid.
What melting point do you reach to become a liquid?
Each substance has a specific melting point (excepting cases of sublimation or thermal degradation).
What is the degrees of the melting point?
Every substance has a different melting point, which means that each substance changes from solid to liquid at a different temperature called the melting point of that substance. The nmelting point of water is 0 degrees celsius.
What point does it become a liquid?
The boiling point of a substance is the point at which that substance will change between being a gas and a liquid. For example, the boiling point of water is 100oC, so water vapour will change to water at this temperature. The boiling point of Methane is -161oC, so any temperature above this, Methane will be in gas form.
Why will it still have a melting point range although a crystal may be pure?
because each compound has different isomers so that is why the melting point range is different.
