Question

Air is necessary for combustion. (True or False). Also write the false statements in their correct form.

• A. True
• B. False

Answer 1

The correct option is A True

Combustion

• Combustion is a chemical process in which a substance burns in the presence of oxygen to give off heat.
• The substances which undergo combustion are known as combustible substances.
• During combustion, heat is accompanied by light, either as a flame or as a glow.
• Since air is a mixture of gases and oxygen that helps in burning also called a supporter of combustion, therefore, air is necessary for combustion.
• Example of combustion reaction: Charcoal burns in air to give carbon dioxide and heat.

$\underset{\mathrm{Carbon}}{\mathrm{C}\left(\mathrm{s}\right)}+\underset{\mathrm{Oxygen}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Carbon}\mathrm{dioxide}}{{\mathrm{CO}}_2\left(\mathrm{g}\right)}+\mathrm{Heat}$

Hence, the given statement is true.
