The temperature increases when energy is released during a chemical reaction.
exothemic energy
A chemical reaction need an activation energy to start.
Chemical changes can either absorb or release energy. When a chemical reaction releases energy, it is called an exothermic reaction. This means that the products of the reaction have lower energy than the reactants, and the excess energy is released in the form of heat or light.
Chemical energy is released during a chemical reaction.
It depends. There are two types of chemical reaction int his sense. Exothermic reactions release energy and endothermic reactions absorb it.
Energy can either decrease or increase during a chemical reaction depending on whether it is an exothermic reaction (energy is released) or an endothermic reaction (energy is absorbed). In an exothermic reaction, energy is released in the form of heat, and in an endothermic reaction, energy is absorbed from the surroundings.
During a chemical reaction, energy is either absorbed or released. If energy is released, it is usually in the form of heat. If energy is absorbed, the reaction requires an external energy source to proceed.
During a chemical reaction, chemical bonds between atoms are broken and new bonds are formed, resulting in the rearrangement of atoms to create new substances. In a chemical reaction, the total amount of mass and energy remains constant due to the law of conservation of mass and energy. A chemical reaction can involve the release or absorption of energy in the form of heat, light, or electricity.
