Why is it difficult to get petrol and diesel?
Answers
Answer:
Petrol and diesel come from crude oil, which comes from deep underground. Crude oil is refined to make petrol (in America this is known as gasoline) or diesel.
An engine’s purpose is to convert the chemical energy of the fuel into kinetic energy, movement! Petrol or diesel is burnt in the internal combustion engines of vehicles. Like power stations, engines use heat and pressure to move moving parts that drive the car forwards.
Answer:
Crude oil is often a dark, sticky liquid that cannot be used without changing it. The first part of refining crude oil is to heat it until it boils. The boiling liquid is separated into different liquids and gases in a distillation column. These liquids are used to make petrol, paraffin, diesel fuel etc.
