The melting point range of a substance has a relationship to its purity. The more pure the substance, the lower the range, and vice versa.
ex. "Aspirin has a published melting point of 138*C. If you experimentally test the melting point of a substance that is thought to be aspirin and find it to be 132-138*C, that melting range would be broader than the published definite point of 138*C. Therefore, the substance under experiment would contain more impurities (making it less pure) than actual aspirin.
It indicates that the substance is impure.
what is the melting point and boiling point of substance
The melting point of a substance varies according to the properties of that substance
melting point
The melting point of aluminium is 660,32 0C.
This is the definition of the melting point of an element or substance. The melting point is when a solid begins to turn into a liquid. A substance also has a boiling point and freezing point.
what is the melting point and boiling point of substance
it decreases.
Celsius is a measure of temperature not a substance, and therefore it has no melting point. What is the melting point of what material in Celsius? [You haven't named the substance you want the melting point of/for]
The melting point of a substance varies according to the properties of that substance
It indicates that the substance has turned to a liquid.
what the heck are you asking? the melting point is not a substance. it's a temperature in which the substance starts to melt
does the melting point of a substance change over time
melting point
Knowing the melting point of a substance provides information to determine what the substance is if its unknown. If you are making a substance, checking the melting point will let you know if you have made what you set out to make, (because impurities can mess up the melting point)
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.
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.
The melting point would also be 21 degrees because the freezing point and melting point of a pure substance is exactly the same.
