Energiändring
Energiändring refers to the change in the amount of energy within a system. Energy is the capacity to do work, and it can exist in many forms, such as kinetic, potential, thermal, chemical, and electrical. In any process, the total energy of an isolated system remains constant, according to the law of conservation of energy. However, within a specific system, energy can be transformed from one form to another or transferred between the system and its surroundings.
When we talk about an energiändring, we are quantifying how much energy has been added to or
