The boiling point and separation of the petroleum oil
The boiling point
The boiling point is the temperature at which a matter begins to change from a liquid state to a gaseous state , The change of matter from liquid state to gaseous state is know as boiling , and the temperature at which the matter begings to boil is called the boiling point .
The pressure affects the boiling points , and the boiling points of the liquids vary widely at the normal atmospheric pressure , and because of this variation in the boiling points , two or more liquids can often be separated by a process called the fractional distillation .
Life application on boiling process
The separation of the petroleum oil depends on the difference between them in their boiling points , The separation of the components of oil can be done by heating the crude oil , then separating each substance at its boiling point .
The boiling point is the temperature at which the vapour pressure of the substance is equal to the atmospheric pressure , The boiling point depends on the pressure , whereas the pressure increases , the boiling point increases .
The pressure pans are used for fast cooking as they raise the pressure so , the boiling point increases and the food is cooked faster .
