heat and oxygen are produced when it is burnt. if my answer is wrong call me on 07734 940264
Yes. Gasoline and diesel engines are both heat engines.
it is burnt using heat
The wasted energy when coal is burnt is called waste heat. This is the energy that is not converted into useful work during the combustion process and is released into the environment as heat.
When coal is burnt, the energy transformation that occurs is from chemical energy stored in the coal to thermal energy in the form of heat, which can be used to generate electricity or heat for various applications.
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.
When coal is burnt, it releases thermal energy in the form of heat. This heat energy is generated by the combustion process, which involves burning the coal in the presence of oxygen to produce heat and other byproducts.
fuel, coal
When coal is burnt, the energy lost in the form of heat and pollutants such as carbon dioxide and ash is considered as not useful energy. This includes waste heat that is not converted into useful work or electricity.
Heat, and light.
The chemical energy in the wood that allows it to burn is transferred to heat, light, and sound energy.
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.
