For example burning of gas.
when we heat the salt there chemical reaction is takes place
Exothermic reaction gives free heat (energy).
A reaction that gives off heat . A reaction that takes in heat is ENDOTHERMIC.
A chemical reaction that gives off heat ... like burning a candle.
An exothermic reaction is a chemical reaction that releases energy in the form of heat. This means that the reaction gives off more energy than it absorbs, resulting in an increase in temperature in the surroundings. Examples of exothermic reactions include combustion and neutralization reactions.

exothermic reactions-gives off heat
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.
