Question

♥Hola mates♥

Define the following:-

★★★★★★★★★★★★★★★★


1: Combustion

2: Calorific value

Answer 1

Calorific value is defined as the amount of heat energy produced on complete combustion of 1 kilogram of a fuel. It is expressed in a unit called kilojoule per kg. The higher the calorific value of a fuel, the more is its efficiency.

Combustion, or burning,[1] is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.

Answer 2

heya...!!!

✔here is ua answer:

___________________________________________❤

➡ Calorific Value: The amount of heat generated, produced, liberated by during from one kilogram of specific substance is Calorific Value.

➡ Combustion: Combustion is a chemical process or a reaction between Fuel (Hydrocarbon) and Oxygen. When fuel and oxygen react it releases the heat and light energy. Heat and light energy then result in the flame. So, the formula for Combustion reaction is Hydrobcarbon + Oxygen = Heat energy.

hope it helps...!!!!❤
