coal have chemical energy
chemical energy is stored in coal
Coal contains potential energy, which is energy that is stored within an object based on its position, composition, or state. When coal is burned, it releases this stored energy in the form of heat and light.
The energy in a lump of coal is primarily stored chemical energy that is released when the coal is burned. This energy is typically used for electricity generation or heating purposes. The amount of energy in coal can vary depending on factors such as its type and quality.
Natural Gas, Solar Energy, Wind Power. The best type of coal and the most energy efficient is the coal that's still buried in the ground... LEAVE IT THERE!! TJ Daniels poet
One type of energy released and not useful when coal is burnt is thermal energy in the form of waste heat. This energy is often lost to the environment in the process of burning coal and is not harnessed for productive use.
Coal produces around 24-33 megajoules of energy per kilogram when burned. The energy output can vary depending on the type and quality of the coal.
Chemical energy is stored in coal, as it is a fossil fuel composed mostly of carbon. This energy is released when coal is burned through combustion processes to generate heat and electricity.
Chemical potential energy.
chemical energy
On average, coal has an energy content of about 24,000,000 joules per kilogram. This energy content can vary depending on the type and quality of the coal.
You could argue that it has stored potential energy.
Energy cannot be 'made' or 'destroyed'. It can simply be transformed to a different type of energy. Coal contains chemical energy, which will for example, be converted to heat energy in say a coal fired industrial boiler.
