What is petrol?

Petrol, also known as gasoline, is a fossil fuel that is used as a fuel source for internal combustion engines in vehicles. It is a complex mixture of hydrocarbons, typically containing between 6 and 10 carbon atoms per molecule. Petrol is obtained from crude oil through the process of refining, where it is separated from other components such as diesel, kerosene, and lubricating oils. The price of petrol is influenced by factors such as global demand and supply, geopolitical tensions, and tax policies. It is a non-renewable resource and is a significant contributor to air pollution and climate change. Over the past few decades, there has been increasing interest in developing alternative sources of fuel, such as electric vehicles, to reduce dependence on petrol.
