Why is Octanol an energy efficient fuel?
Octanol is considered an energy efficient fuel due to its high energy density, which is approximately 30% higher than gasoline. This means that Octanol can provide more energy per unit volume, allowing it to generate more power and efficiency when used as a fuel for engines or vehicles. Additionally, Octanol has a lower risk of evaporation compared to other biofuels, reducing energy losses during storage and transportation.
What provide 39kj of energy per gram?
Fats provide approximately 9 calories (37.7 kJ) of energy per gram.
How many joules of energy are used when a match is burned?
The energy liberated by burning the whole match is the weight (0.2grams ?) times heat of combustion of the wood - about 20kJ per gram so a few kilojoules as you almost never burn it completely. Mike
Are Fats used for energy True or false?
True. Fats are a source of energy for the body, providing more than double the amount of energy per gram compared to carbohydrates or proteins. They are broken down into fatty acids and stored in the body's adipose tissue to be used as fuel when needed.
What is the specific energy joules per gram of bioethanol?
The specific energy of bioethanol is approximately 26.8 megajoules per kilogram, which is equivalent to 0.0268 joules per gram.
Which fuel gives off the most energy if one gram is burned out of coal natural gas or oil?
Natural gas, it gives off 55kj per gram whereas coal gives off 30kj and oil 45kj.
Which fuel gives most energy when one gram is burnt?
Hydrocarbons like gasoline or diesel generally provide the most energy when one gram is burnt, as they have high energy densities. Other fuels like hydrogen gas or methane can also provide a lot of energy per gram when burned.
What fuel produces more energy per gram burned- Ethanol or paraffin?
Paraffin produces more energy per gram burned compared to ethanol. This is because paraffin has a higher energy density due to its chemical composition, which allows it to release more energy when combusted. Ethanol, on the other hand, has a lower energy content per gram.

Which types of fuels give out energy when burned?
Fuels such as gasoline, coal, natural gas, and wood all release energy when they are burned. This energy is in the form of heat and light, which can be harnessed for various purposes such as heating, electricity generation, and transportation.
What is the amount of energy released when nutrients are burned?
The amount of energy released when nutrients are burned can vary depending on the type of nutrient. On average, one gram of carbohydrate releases about 4 kilocalories of energy, one gram of protein releases about 4 kilocalories, and one gram of fat releases about 9 kilocalories. This energy is utilized by the body for various functions such as metabolism, physical activity, and maintaining body temperature.
What nutrient that provides 4 calories per gram and gives the body energy?
carbohydrates
What Nutrient provides 4 calories per gram and gives the body energy?
carbohydrates
What fuel provides the greatest quanity of energy per gram?
Pure fat provides the greatest quantity of energy per gram compared to other fuels, containing approximately 9 calories per gram, while carbohydrates and protein contain about 4 calories per gram.
Is sugar a fuel?
It is impossible to be a fuel, because it does not have the correct properties to power an engine. Sugar could be considered a fuel for the body. Sucrose is an easily assimilated macronutrient that provides a quick source of energy. Sucrose, as a pure carbohydrate, has an energy content of 3.94 kilocalories per gram (or 17 kilojoules per gram).
Which ingredients give th body energy?
There are four basic food categories that give the body calories (energy); fat, carbohydrate, protein, and alcohol. Fat gives 9 calories per gram. Carbohydrates and proteins give 4 calories per gram. Alcohol gives 7 calories per gram.
Which provides more energy per gram of fuel fission or fusion?
Fusion provides more energy per gram of fuel than fission. Fusion reactions release several times more energy compared to fission reactions, making fusion a more efficient and powerful energy source.
