What are combustible matter? Properties and Examples

What is combustible matter?

The combustible matter is any material that can be easily ignited and burned. It is a broad term that includes solids, liquids, and gases. Some common examples of combustible matter include:

Solids: Wood, paper, cloth, plastics, rubber, coal, and charcoal.

Liquids: Gasoline, kerosene, diesel fuel, alcohol, and paint thinner.

Gases: Hydrogen, methane, propane, butane, and natural gas.

Combustible matter can be a fire hazard if it is not stored or handled properly. It is important to keep combustible matter away from heat, sparks, and flames. It is also important to store combustible matter in approved containers that are designed to prevent leaks and spills.

The properties of combustible matter

The properties of combustible matter are given below:

Flash point: The lowest temperature at which a liquid will give off enough vapor to form an ignitable mixture with air.

Autoignition temperature: The minimum temperature at which a material will ignite without an external source of ignition.

The heat of combustion: The amount of heat released when a material burns completely.

The flammability of combustible matter is determined by its flash point and autoignition temperature. Materials with a low flash point are more flammable than materials with a high flash point. Materials with a low autoignition temperature are more likely to ignite spontaneously than materials with a high autoignition temperature.

The heat of combustion of combustible matter is important because it determines the amount of energy that is released when a material burns. Materials with a high heat of combustion release more energy when they burn, which can make them more dangerous.

It is important to be aware of the properties of combustible matter in order to prevent fires and other accidents. By understanding the risks associated with combustible matter, you can take steps to keep yourself and others safe.
