Gasoline can be released into the Earth's environment as an uncombusted liquid fuel, as a flammable liquid, or as a vapor by way of leakages occurring during its production, handling, transport and delivery. [83] Gasoline contains known carcinogens, [84] [85] [86] and gasoline exhaust is a health risk. [75]
This is an extended version of the energy density table from the main Energy density page: ... Gasoline + Oxygen –> Derived from Gasoline: 13.3 [citation needed]
The higher the energy density of the fuel, the more energy may be stored or transported for the same amount of volume. The energy of a fuel per unit mass is called its specific energy. The adjacent figure shows the gravimetric and volumetric energy density of some fuels and storage technologies (modified from the Gasoline article).
Gasoline prices go from 36 cents a gallon in 1972 to over 50 cents a gallon in 1973. March 18, 1974 - At an OPEC meeting, seven members lift the ban on exports to United States.
The fuel consumption is an equivalent measure for cars sold outside the United States, typically measured in litres per 100 km traveled; in general, the fuel consumption and miles per gallon would be reciprocals with appropriate conversion factors, but because different countries use different driving cycles to measure fuel consumption, fuel ...
It has a volumetric energy density of 17 Megajoules per liter (compared to 10 for hydrogen, 18 for methanol, 21 for dimethyl ether and 34 for gasoline). It must be compressed or cooled to be a liquid fuel, although it does not require cryogenic cooling as hydrogen does to be liquefied.
The density of an ideal gas is =, where M is the molar mass, P is the pressure, R is the universal gas constant, and T is the absolute temperature. This means that the density of an ideal gas can be doubled by doubling the pressure, or by halving the absolute temperature.
Natural gasoline is a liquid hydrocarbon mixture condensed from natural gas, similar to common gasoline (petrol) derived from petroleum. The chemical composition of natural gasoline is mostly five- and six-carbon alkanes ( pentanes and hexanes ) with smaller amounts of alkanes with longer chains. [ 1 ]
