Question

What is the physical state of gasoline at room temperature?

Answer 1

To solve this question we first need to know what is gasoline. A fuel that is derived from fossil fuel petroleum is known as gasoline. However, it is also called petrol in the commonwealth countries like Britain, India, etc.

Complete answer:
Fuels that contain organic molecules such as hydrocarbons and are formed in millions of years by natural processes like anaerobic decomposition of buried dead organisms are known as fossil fuels.
Gasoline is prepared from refining fossil fuel crude oils. First, the crude oil is heated until it boils and then the boiling liquid is separated into liquids and gases in a distillation column. Among paraffin, diesel, etc., gasoline is also produced.
Since gasoline is a derivative of petroleum that is a fossil fuel, upon combustion, releases energy in the form of heat and light.
Gasoline has components like isooctane having a formula ${{C}_{8}}{{H}_{18}}$, butane having a formula ${{C}_{4}}{{H}_{10}}$, 3-ethyltoluene, and MTBE (methyl tert-butyl ether) which acts as an octane enhancer.
We know that hydrocarbons that have more than 4 carbon atoms exist as a liquid at STP or room temperature. Since gasoline contains isomers of pentane and octane, it will exist in the liquid state.
So, Gasoline is liquid at room temperature.

Note:
It should be noted that gasoline is highly flammable. Even though gasoline is liquid at room temperature, it has been observed that the molecules in the top layer of the liquid gasoline escape into the gaseous phase easily. The boiling temperature of gasoline is very low at 36${}^\circ$C.
