Gasoline is made when refineries break down the hydrocarbons found in crude oil. Crude oil is formed from the remains of animals and aquatic plants that lived billions of years ago and have been covered in sediment and exposed to high temperatures and extreme pressure.


Gasoline and water do not mix because they have different density levels, or mass per unit volume. Water has a density of 1 gram per milliliter, while gasoline has a density of 0.8 gram per milliliter.


The patent for the process to make what people now know as gasoline was filed in 1913. The forerunner of gasoline was around in the 1800s before the invention of the internal combustion engine, but it was only known as a useless by-product of the process used to make kerosene for oil lamps.


Gasoline can freeze when exposed to cold enough temperatures for an extended period of time. However, gasoline does not have a specific freezing point, as the various hydrocarbons and other substances that it contains all freeze at different temperatures.


Commodity prices are notoriously hard to predict; however according to Forbes, gasoline prices are not likely to rise greatly during 2015. However if oil supply is significantly reduced, gas prices may rise.


The symptoms of bad gas involve a lean misfire, which creates a P0300 code in newer cars, engine detonation and pinging, sputtering and stalling. These occur because the bad gas fails to keep the fuel system clean and introduces contaminants that can clog fuel filters, fuel pumps and fuel injectors.


There is no single evaporation rate for gasoline because the rate varies based on additives in the gasoline and the environmental conditions where it is stored. In an open container at room temperature, the volatile components of gasoline begin to evaporate immediately.


The boiling point of gasoline ranges between 104 and 392 degrees Fahrenheit. The wide range of boiling points is due to the many different blends of components available to provide different characteristics such as higher octane, lower fuel deposits and overall volatility.


Factors that determine the price of gasoline include the current price of crude oil, the costs of oil refinement, current tax rates and the expenses incurred by petroleum companies to market gasoline to consumers. Of these factors, the price of crude oil is the largest determining factor in gasoline


Gasoline may freeze at temperatures between negative 40 degrees Fahrenheitand negative 58 F. The exact freezing temperature depends on the properties of the individual constituents in gasoline.
