Question

“gasoline boils at a relatively low temperature (about 150 C). the kerosene is removed at around 200C, followed by diesel oil at 300C and fuel oil at around 370C”.

What topic is the teacher most likely talking about?
A. distillation of a mixture
B. filtration of pure substance
C. evaporated of a mixture
D. sorting of a pure substance

Answer 1

A is the correct answer (distillation of a mixture)

Step-by-step explanation:

Answer 2

A. distillation of a mixture

Step-by-step explanation:

The topic the teacher is most likely talking about is the distillation of a mixture.

During fractional distillation, a mixture is separated into it constituents based on differences in their boiling point.

• A liquid made up of denser hydrocarbon such as crude oil is fed into the distillation chamber.
• It is then heated.
• At different boiling point of its constituents, the fractions begins to separate out.
• They rise in the column.
• The condensate is then collected.

This process is the distillation of mixture.
