I would think D but I'm probably wrong
I assume that you want to mean filtration and not fileration that is wrong anyway
what is the correct answer
I did but I did not see the answer, I want to get a good grade on this
what did you understand from the reading?
A)Fractional distillation https://en.wikipedia.org/wiki/Fractional_distillation
I will post the next question and tag both of you in it
Once it enters the modern refinery, crude oil goes through a process called fractional distillation. This process separates the different components of crude oil so that they can be further refined. Fractional distillation begins when the crude oil, which is a mixture of different hydrocarbons, is put into a high-pressure steam boiler. This is a tank that makes the oil boil and turn to vapor, much like boiling water turns into water vapor. The crude oil is heated to temperatures up to 1112° Fahrenheit.
