Question

The …………. given out during combustion is used to generate electricity

Answer 1

• Burn fossil fuels such as coal, diesel, petrol, and LPG for a number of purposes. Fuel is a substance that burns rapidly in the presence of oxygen to give a large quantity of useful heat, along with water vapour and carbon dioxide.
• Fuel + oxygen → water vapour + carbon dioxide + heat .
• The heat given out in combustion is harnessed as energy, which is used to drive vehicles, cook, run machines in industries, and generate electricity.
• The water vapour and carbon dioxide produced during combustion escape into the air.

Therefore, The heat given out during combustion is used to generate electricity.
