Chapter Review:

The chemical process in which a substance reacts with oxygen and gives heat is called combustion.
The substance that undergoes combustion is said to be combustible. It is also called a fuel.
The lowest temperature at which a substance catches fire is called its ignition temperature.
The amount of heat energy produced on complete combustion of 1 kg of a fuel is called its calorific value. Its unit is kilojoules per kg (kj/kg)
The substances which have very low ignition temperature and can
easily catch fire with a flame are called inflammable substances. Examples of inflammable substances are petrol, alcohol, Liquified Petroleum Gas (LPG), etc.
There are three different zones of a flame - dark zone, luminous zone and non-luminous zone.
Phosphorus which burns in air at room temperature.
The type of combustion in which a material suddenly bursts into flames, without the application of any apparent cause is called spontaneous combustion.
A large amount of gas formed in the reaction is liberated. Such a reaction is called explosion.
The sources of heat energy for domestic and industrial purposes are mainly wood, charcoal, petrol, kerosene, etc. These substances are
called fuels.
Combustion of most fuels releases carbon dioxide in the environment.
Increased concentration of carbon dioxide in the air is believed to cause global warming.
Oxides of sulphur and nitrogen dissolve in rain water and form acids. Such rain is called acid rain.
Incomplete combustion of a fuel gives poisonous carbon monoxide gas.
An ideal fuel is cheap, readily available, readily combustible and easy to transport. It has high calorific value. It does not produce gases or
residues pollute the environment.
