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.

To calculate the mass of octane burned, we can use the heat of combustion of octane which is 5470 kJ/mol. First, convert the given energy to kilojoules per mole. Then, use the molar mass of octane to convert moles to grams. This will give you the mass of octane that must be burned.
When kerosene is burned, it produces carbon dioxide, water vapor, and heat energy. The heat energy can be harnessed for various purposes, such as heating or generating electricity.
A burned bagel is a chemical change because the heat causes the sugars, proteins, and fats in the bagel to react with oxygen in the air, resulting in the formation of new substances with different properties. This irreversible change alters the composition of the bagel.
Some components are thermally decomposed and others are burned.
When fossil fuels are burned they give off heat, the reason why we use them. Then they give gasses such as CO2 for example.
Coal is burned to produce heat The heat is used to produce steam in a boiler. The steam is used to turn a turbine and generator set. This causes electricity to run through the wires.
When fuel is burned in a fire, it releases energy in the form of heat and light. The heat causes the fuel to break down into glowing hot particles that emit light as they burn. This is what creates the bright flame that we see in a fire.
When combusted, methanol releases about 22.7 megajoules of heat per liter of fuel burned.

Hi, when fuel is burned, energy in the form of heat is given off. hope this helps

Friction causes heat. Heat is a source of energy.
mayby because you might get burned your self , move the patient to a safer area
False. Materials that are burned to produce heat or power are known as fuels, not energies. Energy is the capacity to do work or generate heat, while fuels are substances that can be burned to release energy.
