For example burning of gas.
when we heat the salt there chemical reaction is takes place
Exothermic reaction gives free heat (energy).
A chemical reaction that gives off heat ... like burning a candle.
Exothermic (gives off heat - and light!).
An exothermic reaction is a chemical reaction that is done by the release of heat. It gives out energy to its surroundings. The energy needed for the reaction to occur is less than the total energy released.

Exothermic reaction gives free heat (energy).
Exothermic Reaction.
An endothermic reaction is one that consumes heat.
combustion
A chemical reaction that gives off heat ... like burning a candle.
A chemical change that gives off heat. Burning paper would be an example.
Boiling happens when you heat a liquid, until it evaporates. Effervscense is some gas that escapes, due to some chemical reaction - but not necessarily due to heat.Boiling happens when you heat a liquid, until it evaporates.

The heat is released in the environment.
A fire is an example of chemical heat. The reaction of oxygen with combustible materials, simplest case, carbon say in coal, gives carbon dioxide and heat.
