Question

write note on calorific value
​

Answer 1

Explanation:

Calorific value is the amount of heat energy present in food or fuel and which is determined by the complete combustion of specified quantity at constant pressure and in normal conditions. It is also called calorific power. ... If the heat contained in the water vapour could be recovered then it has high calorific value.

Answer 2

Answer:

Calorific Value:- the amount of heat released by a unit weight or unit volume of a substance during complete combustion.

• The unit of calorific value is kilojoule per kilogram ( KJ/Kg)

Explanation:

▶ The efficiency of fuel or food mainly depends on the calorific value. If the value is high, its efficiency will also be high. If the value is low, its efficiency would also decrease. Calorific value is directly proportional to its efficiency.

• LPG has more calorific value when compared to diesel, petrol, and kerosene
