When fuels are burnt, chemical energy stored in the fuel is converted into thermal energy in the form of heat. This heat energy is then used to raise the temperature of a surrounding medium or to perform work, such as in an engine or power plant. The combustion process releases energy by breaking the chemical bonds within the fuel molecules, resulting in the production of heat and light.

When fuels are burnt what happens to the chemical potential energy?
When fuels are burnt, the chemical potential energy in the fuels is converted into heat and light energy. Initially, such energy will be converted to heat. In a fire, part of that will be radiated away as infrared radiation or light; it is also common that the heat will increase the pressure and make things expand - which is what happens in a gasoline or diesel engine.
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.
Why are fosil fuels burnt?
Fossil fuels are burned to generate energy in the form of heat or electricity. This energy is used for various human activities such as transportation, heating, and powering electrical devices. However, burning fossil fuels releases carbon dioxide and other greenhouse gases that contribute to climate change.
Which gas is produced when fossil fuels burnt?
When fossil fuels are burnt, carbon dioxide (CO2) is produced as a byproduct along with water vapor and other pollutants like carbon monoxide and nitrogen oxides.
What is the process of converting the chemical energy in fossil fuels to electrical energy?
Fossil fuels are burned to produce heat, which is used to boil water and create steam. The steam drives a turbine connected to a generator, where the mechanical energy is converted into electrical energy by electromagnetic induction. The generated electricity is then distributed through power lines to homes and businesses.
What are the two forms of energy released when fuels are burnt?
Heat, and light.
What energy is released by fossil fuels?
Fossil fuel are burnt to release HEAT
What is useful energy transfer when coal is burnt?
Chemical energy is transferred to electrical energy! :) :p
When fuels are burnt the chemical energy changes to what?
When fuels are burned, the chemical energy in the fuels is converted into heat energy and light energy. This process releases energy stored in the chemical bonds of the fuel molecules, resulting in heat and light as byproducts.
How are fossil fuels used to generate energy?
Fossil fuels (coal, oil and natural gas) are burnt in vehicles and electricity power plants. This releases the energy.
How is the energy of the nonrenewable oil harnessed captured and transferred?
Oil is pumped up from beneath the surface of the Earth and (often) refined into various products and fuels. Fuels are burnt to release their energy.
What is the process of converting the chemical energy in fuels to electrical energy?
A simple answer is that fossil fuels are burnt. The heat is used to produce steam which drives mechanical turbines and dynamos, which then produce electricity.
Gas is burnt to cook a meal is it an energy conversion or an energy transfer?
How does it happen? If there's a chemical change, it's energy conversion, if it's a physical change, it's energy transfer.
When fuels are burnt what happens to the chemical potential energy?
When fuels are burnt, the chemical potential energy in the fuels is converted into heat and light energy. Initially, such energy will be converted to heat. In a fire, part of that will be radiated away as infrared radiation or light; it is also common that the heat will increase the pressure and make things expand - which is what happens in a gasoline or diesel engine.
Are fossil fuels renewable non renewable or inexhaustible?
Fossil fuels are non-renewable. Once we've burnt them, they're gone!
How does fossil fuels generate electrical energy energy transfer diagram?
Well, fossil fuels are burned which heat boilers, this creates steam which spins turbinescreating electricity.
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.
