True or false and why: At a refinery, the oil is heated to condense the products?

I would say false.





Crude oil is indeed heated, that part is true. However, the heating doesn't condense anything.





The process is called cracking. The process takes long hydrocarbon chains and breaks them into smaller ones. The process can take place by a number of means. At the very basic level, crude is heated under pressure to break the molecules.





On a very high level, the resulting hydrocarbon chains are distilled, treated, and seperated into different products. A barrel of crude can produce any or all of the following:





gasoline


diesel oil


kerosene


heating oil


jet fuel


other chemicals





So the resulting process seperates the products rather than condensing them.





How Stuff Works has a pretty good article on oil refining. It may be worth a look:

I think so...
