Hydrogen fuel gives off the most heat per gram when burned, producing about 141.9 megoujoules (MJ) per kilogram. This high energy density is due to hydrogen's low molecular weight and its combustion reaction with oxygen, which produces water as a byproduct. In comparison, hydrocarbons like gasoline and natural gas yield less energy per gram, making hydrogen one of the most efficient fuels in terms of heat output.

What causes wood and gas to give off heat when they're burned?
When wood or gas is burned, heat is produced due to the process of combustion. Combustion is a chemical reaction that takes place between the fuel (wood or gas) and oxygen in the presence of heat, resulting in the release of energy in the form of heat and light. The fuel undergoes oxidation, breaking down into simpler molecules and releasing heat energy in the process.
How much energy per gram of hydrogen is produced when hydrogen gas is being burned?
The combustion heat of hydrogeh (HHV) for 1 g is 141,8 kJ.
What is the heat of combustion of cetyl alcohol?
The heat of combustion of cetyl alcohol is approximately 41.7 kJ/g. This value represents the amount of heat released when one gram of cetyl alcohol is completely burned in oxygen.
What is most natural gas burned for?
Most natural gas is burned for electricity generation and heating in homes and businesses. It is also used as a fuel in industrial processes, such as in manufacturing and in the production of chemicals.
Which is a nonrenewable resource used to heat homes?
Natural gas is a nonrenewable resource commonly used to heat homes. It is a fossil fuel that is burned to produce heat for residential heating systems.
When a fuel is burned what is lost as heat?
Hi, when fuel is burned, energy in the form of heat is given off. hope this helps
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.
When a fossil fuel is burned what energy is converted into kinetic energy?
When a fossil fuel is burned, the chemical energy stored in the fuel is converted into heat energy. This heat energy is then used to heat water, produce steam, and drive turbines to generate kinetic energy, which can be used to produce electricity or power machinery.
Name a type of rock that is burned as a fuel?
Coal is a type of rock that can be burned as a fuel source to generate heat and electricity.
What is something that can be burned to produce heat and power?
Wood, coal, oil, natural gas, and biomass are all examples of materials that can be burned to produce heat and power.
What does energy release when fuel is burned?
When fuel is burned, energy is released in the form of heat and light. This is because the chemical bonds in the fuel molecules break, releasing stored energy in the form of heat that can be used for various applications, such as heating, powering engines, or generating electricity.
Is thermal energy released when fuel is burned?
Yes, thermal energy is released when fuel is burned. The combustion reaction converts chemical energy stored in the fuel to thermal energy, which is released as heat. This heat energy can then be used for various applications, such as heating or generating electricity.
What happen to fuels so that they can produce heat and light?
Usually, fuel is burned to achieve this.
When a fuel is burned what is it combined with?
When a fuel is burned, it is combined with oxygen in a process called combustion. The fuel undergoes a chemical reaction with oxygen, producing heat, light, and various byproducts such as carbon dioxide and water vapor.
What is any material that is burned for heat or power?
A material that is burned for heat or power is commonly referred to as a fuel. This process is known as combustion, where the fuel reacts with oxygen to release energy in the form of heat. Common examples of fuels include wood, coal, natural gas, and gasoline.
How does fossil fuel work?
You burn it; it gives off heat; you use the heat.
The 2 elements present in a material that gives off heat when burned?
