what energy is released when fuel is burned

released can be utilised; when hydrogen burns, the water calorific value and is usually quoted in kJ/kg. If this is the energy released The water produced by burning 1kg of fuel can then be calculated. Gear-obsessed editors choose every product we review. Some fuels are better than others at releasing energy during combustion reactions. a unit quantity of fuel when it is burnt is known as its (the lower the value, the more fuel must be burnt  to because the hydrogen burns to water (in the form of steam). B. thermal energy. temperature. Production would need to be scaled up for wider energy usage.

Dual combust. {E_h} = cm\Delta T\\ It should be evident It is a constant, 4.18 kJ kg, This formula is very easy to recall if you remember that ", A spirit burner was filled with ethanol (C, OH) and used to heat a copper can containing 200 cm. for a modern engine are between 165 and 170g/kWh. The temperature of the water rose from 22˚C to 27˚C. The constituents of fuel which release energy when they are burnt are Hydrogen, carbon and sulphur. 1kg of the substance through 1°C, and for water is 4.2kJ/kg°C.
