FIRE

O2 + CO2 + H2 ==> HEAT + Light

When oxygen present in the air combines with carbon and hydrogen present in the fuel, energy is released in form of heat and light and this is FIRE. Requirements for making fire are – fuel, heat, and oxygen. Fuel and oxygen are easily available to us in the form of wood, oil, and gas, and from air respectively. But providing the heat to an object to make it catch fire is the tricky part. Every fuel burns at a particular temperature which is ‘flashpoint’ or ‘kindling temperature’.

Fire will be a good servant if you handle it with care but it can be a cruel master if it goes out of control.
