What is energy content in fuels?
Energy content is the amount of heat produced by the burning of 1 gram of a substance, and is measured in joules per gram (J/g). You can determine energy content of a fuel by burning an amount of the fuel and capturing the heat released in a known mass of water in a calorimeter.
Which fuel has the highest energy content?

hydrogen
The highest energy density fuel is hydrogen, which is also the simplest chemical component in existence. Gasoline, which is derived from refining crude oil, contains much more energy than coal (twice the lower grade bituminous) or wood (three times).
What is the energy content of petroleum?
44 MJ/kg
The higher the energy density of a system or material, the greater the amount of energy it has stored. A material can release energy in four types of reactions….Fuel energy density.
Fuel | Energy density |
---|---|
Crude oil | 44 MJ/kg |
Diesel | 45 MJ/kg |
Gasoline | 46 MJ/kg |
Natural gas | 55 MJ/kg |
What determines the energy content?
Determining the energy content of foods depends on the following: 1) the components of food that provide energy (protein, fat, carbohydrate, alcohol, polyols, organic acids and novel compounds) should be determined by appropriate analytical methods; 2) the quantity of each individual component must be converted to food …

What is the energy content of diesel?
Heating fuels and their energy content.
Energy Source | Unit | Energy Content (Btu) |
---|---|---|
Diesel Fuel | 1 Gallon | 139000 |
Gasoline | 1 Gallon | 124000 |
Natural Gas | 1 Cubic Foot (cu.ft.) | 950 – 1150 |
Heating Oil | 1 Gallon | 139000 |
Which technique is commonly used to determine the energy content in fuels?
B. bomb calorimeter Measurement. an apparatus that can measure heats of combustion, used in various applications such as calculating the calorific value of foods and fuels.

What LNG means?
liquefied natural gas
what is LNG – liquefied natural gas? LNG is natural gas that has been cooled to –260° F (–162° C), changing it from a gas into a liquid that is 1/600th of its original volume.
