What is rapid combustion give an example?
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 meant by spontaneous combustion?
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.
What is the difference between spontaneous combustion and explosion?
spontaneous combustion: The combustion in which substances suddenly burst into flames, without the application of any apparent cause is called spontaneous combustion. The combustion in which sudden reactions take place on ignition of some substances to produce heat, light, and sound is called explosion.
What are the examples of spontaneous combustion?
Spontaneous combustion: The ignition of a substance or body from the rapid oxidation of its own constituents without heat from any external source is known as spontaneous combustion. Example: Phosphorous and sulphur start burning instantaneously; at room temperature.
How does co2 control fire?
Carbon dioxide extinguishes work by displacing oxygen, or taking away the oxygen element of the fire triangle. The carbon dioxide is also very cold as it comes out of the extinguisher, so it cools the fuel as well.
How do we get the supply of carbon dioxide Class 8?
Answer: In a soda-acid type fire extinguisher, sodium hydrogen carbonate (NaHCO3) reacts with sulphuric acid to give out carbon dioxide.
What is the ignition temperature of phosphorus Class 8?

What is the ignition temperature of kerosene?
approximately 295 °C
Which has highest ignition temperature?
Coal
Does paper have high ignition temperature?
Most types of paper burn at 233 degrees Celsius (or 451 degrees Fahrenheit). We have new and used copies available, in 0 edition – starting at . If you aren’t familiar with the book, “Fahrenheit 451” by Ray Bradbury, it was named such because paper begins to burn at 451°F. Ignition temperature of paper is very low.
What is ignition temperature example?
