Exothermic is the term you are looking for. This means that more energy is released from a chemical reaction than it took to initiate it. Combustion is an example of this type of reaction. The opposite of this is the endothermic reaction where a constant influx of heat is needed to initiate and continue the reaction, leading to an overall lowering of the temperature of the system if more heat is not introduced from the outside. Melting ice is an example of this.
In an exothermic reaction, the energy term appears as a product in the chemical equation. This indicates that energy is released as the reaction proceeds, resulting in a net decrease of energy in the surroundings.
The general term for a chemical reaction that releases heat is an exothermic reaction. The energy released is called enthalpy.A reaction that releases energy is called an exothermic reaction.
The term for the amount of energy needed for a chemical reaction to start is called activation energy. It is the energy required to initiate a reaction by overcoming the energy barrier between reactants and products.
An endothermic reaction.
The chemical term for heat transfer in a reaction is "enthalpy." Enthalpy is a thermodynamic quantity representing the heat content of a system and is often used to quantify the amount of heat released or absorbed during a chemical reaction.
The general term for a chemical reaction that releases heat is an exothermic reaction.
Exothermic reaction gives free heat (energy).
The term for releasing energy is ''Flagellation ''
Exothermic reaction gives free heat (energy).
This is known as a coupled reaction, where the energy released from an exergonic reaction drives an endergonic reaction by transferring energy.
Absorbing energy from the surroundings is endothermic. (The opposite - releasing energy to the surroundings - is exothermic).
A chemical reaction whose reactants have less potential energy than the products would be called an endothermic reaction.
