What is a spontaneous combustion easy definition?

spontaneous combustion, the outbreak of fire without application of heat from an external source. Spontaneous combustion may occur when combustible matter, such as hay or coal, is stored in bulk.

Is spontaneous a combustion?

Spontaneous combustion is the phenomenon in which a hydrocarbon (or a chemical substance) substance unexpectedly bursts into flame without apparent cause. In ordinary combustion, the hydrocarbon is deliberately heated to its ignition point to make it burn.

What do you mean by rapid combustion?

Rapid combustion is a form of combustion in which large amounts of heat and light energy are released. This often occurs as a fire. This is used in a form of machinery, such as internal combustion engines, and in thermobaric weapons. Slow combustion is a form of combustion which takes place at low temperatures.

What causes combustion?

To summarize, for combustion to occur three things must be present: a fuel to be burned, a source of oxygen, and a source of heat. As a result of combustion, exhausts are created and heat is released.

What is rapid combustion?

What is the example of rapid combustion?

Rapid combustion: Rapid combustion is a form of combustion in which large amounts of heat and light energy are released. Example: Matchstick burns rapidly on being struck against the sides of a matchbox. Combustion of natural gas, LPG, petrol etc.

What is rapid combustion give one example of rapid combustion?

Burning of LPG is an example of rapid combustion. In this combustion, the combustion of combustible material is complete. LPG burns rapidly and produces heat and light.

What is rapid combustion give two examples?

Rapid combustion 1)The immediate burning of cooking gas in a gas stove to give heat and light. 2)The burning of kerosene oil in kerosene stove.

What are the 3 important things needed for combustion to occur?

Oxygen, heat, and fuel are frequently referred to as the “fire triangle.” Add in the fourth element, the chemical reaction, and you actually have a fire “tetrahedron.” The important thing to remember is: take any of these four things away, and you will not have a fire or the fire will be extinguished.

Which is the best definition of a combustion?

Combustion Definition. Combustion is a chemical reaction that occurs between a fuel and an oxidizing agent that produces energy, usually in the form of heat and light. Combustion is considered an exergonic or exothermic chemical reaction.

What are the ingredients of a combustion reaction?

Fire is a chemical chain reaction which takes place with the evolution of heat and light. In order for a fire to take place there are 3 main ingredients that must be present: Oxygen, Heat and Fuel. In chemistry we call the type of reaction that produces fire a combustion reaction.

When does incomplete combustion occur in a fuel?

Incomplete combustion occurs when there is insufficient oxygen for the fuel to convert completely to carbon dioxide and water. Incomplete oxidation of a fuel may also occur. It also results when pyrolysis occurs prior to combustion, as is the case with most fuels.

How did the internal combustion engine get its name?

The internal combustion (IC) engine is a class of heat engine wherein the chemical energy of fuel is transformed into shaft work. It is so named because combustion occurs inside a combustion chamber that is an integral part of the working fluid flow circuit.
