Question

In an experiment, 4.5 kg of a fuel was completely burnt. The heat produced was measured to be 180,000 kJ. Calculate the calorific value of the fuel.​

Answer 1

Given:-

• In an experiment, 4.5 kg of a fuel was completely burnt.
• The heat produced was measured to be 180,000 kJ.

⠀

To find:-

• Calculate the calorific value of the fuel.

⠀

Solution:-

☆Calorific value of a fuel:-

⇛ Heat produced/Amount of fuel

⇛ 180000/4.5 KJ/Kg

⇛ 40,000 KJ/Kg

⠀

Hence,

• the calorific value of fuel is 40,000 KJ/Kg.

Answer 2

Given :-

• In an experiment, 4.5 kg of a fuel was completely burnt.
• The heat produced was measured to be 180,000 kJ.

To find :-

• Calculate the calorific value of the fuel.

Solution :-

★ Calorific value of a fuel ★

→ Heat produced/Amount of fuel

→ 180000/4.5 KJ/Kg

→ 40,000 KJ/Kg

Hence,

• The calorific value of fuel is 40,000 KJ/Kg.
