eksothermisissa

Eksothermisissa, also known as exothermic reactions, are chemical reactions that release energy in the form of heat or light. These reactions are characterized by a decrease in enthalpy, which is the total heat content of a system. The energy released during an exothermic reaction can be observed as an increase in temperature, the production of light, or other forms of energy such as sound. Common examples of exothermic reactions include combustion, the reaction between an acid and a base to form a salt and water, and the polymerization of certain materials. Exothermic reactions are often used in industrial processes, such as in the production of cement and in the operation of fuel cells. They are also responsible for many natural phenomena, including volcanic eruptions and the heat generated by the human body through metabolism. The opposite of exothermic reactions are endothermic reactions, which absorb energy from their surroundings.
