Combustion and flame
Students will study how combustion takes place and the factors which are required for it.
Moreover, they will also be introduced to ways of controlling a fire. After that, the chapter
discusses the various types of combustion in order to offer detailed information.
Most importantly, the chapter will also explain to students about the types of fuel and their
efficiency. Other than that, the consequences of burning fuel like their harmful effects are also
discussed here. Through this chapter, a student can easily understand all about combustion and
flame. In addition, the different types of flames and their structure are also given here. Thus, it
also plays a great role in making people more careful around fire and being precautious for their
safety.
Combustion and Flame: Chemical Reactions
with Oxygen and Burning Substances to give
off heat is known as combustion.
, Ignition Temperature
● The minimum temperature at which a substance will catch fire
and start burning.
● Factors affecting ignition temperature:
● Type of substance
● Presence of impurities
● Surface area of the substance
● Atmospheric conditions
Inflammable and Non-inflammable Substances
● Inflammable substances:
● Have low ignition temperature
● Readily catch fire
● Non-inflammable substances:
● Have high ignition temperature
● Do not catch fire easily
Fuels and their types
Fuels are solid, liquid, or gaseous substances that produce heat and
light when burned.
Types of Fuels
● Solid fuels: Fossil fuels like coal and wood; also includes
biomass and waste.
● Liquid fuels: Fuels like gasoline, diesel, and biofuels.
● Gaseous fuels: Fuels like natural gas, (LPG)
Controlling Fires
● Fire safety is crucial to prevent and control fires.
