Question

During combustion only dust is released.

• A. True
• B. False

Answer 1

The correct option is B False

Combustion: Combustion is a chemical process in which a substance combines with oxygen to produce new substances and release energy in the form of heat and light.

• Fuels burn in the presence of oxygen to produce carbon dioxide and water vapor as by-products and release energy in the form of heat and light.

$\mathrm{Fuel}+\mathrm{Oxygen}\stackrel{\mathrm{heat}}{\to }\mathrm{Carbon}\mathrm{dioxide}+\mathrm{Water}\mathrm{vapour}+\mathrm{Energy}$

Hence, the given statement is false.
