What is calorific value short answer?

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. The unit of calorific value is kilojoule per kilogram i.e. KJ/Kg.

What is the difference between caloric and calorific?

Usage notes For the senses relating to calories and relating to or producing heat, caloric is the usual form in the US, and calorific is the usual form in the UK.

Which fuel has more calorific value?

hydrogen Calorific value is nothing but the energy contained in a fuel or food, determined by measuring the heat produced by the complete combustion of a specified quantity of it. This is now usually expressed in joules per kilogram. Hence, hydrogen has the highest calorific value.
