The melting point is an indication of purity.
How do the melting and boiling point determine the purity of the substance and identify them?
*usually* melting point is a good indicator of a substance's purity. The technique of melting point determination is used frequently in organic chemistry labs.
Which term is defined as the temperature at which a substance changes from a solid to a liquid state?
melting point
How can you use boiling points and melting points to determine a solid liquid or gas that an element would be in at a certain temperature?
If the temperature is below the melting point then the element is a solid.If the temperature is above the melting point but below the boiling point, then the element is a liquid.If the temperature is above the boiling point, then the element is a gas.

How can you determine if a substances is a solid at room temperature?
Check the melting point of the substance. If the melting point is below room temperature, then the substance is liquid and if the melting point is above room temperature then it is solid.
What is important of 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)
