How is crude oil separated into different fractions?
you use fractional distillation! basically, all the different substances in crude oil have different boiling points, and the column which is used to do fractional distillation has stages with different temperatures. when the substance reaches its boiling point temperature in the column, it turns into liquid and settles there, away from other fuels.
What is the purpose of determining boiling point and melting point?
Boiling point- the temperature and pressure at which a liquid and a gas are in equilibrium. But also, it is very useful in determining the purity of a substance. If the melting point is known of the pure substance, than you can measure the melting point of what you've got and see if it matches. If the melting (or boiling) point is the same, than that is a good indication that the compound you have is what you think it is, and it is pure. If they are different from each other, that indicates that your compound is not pure.
