Fizzling, or dissipation, refers to the process where energy is lost from a system, often in the form of heat or sound. This occurs when energy is transformed from one form to another, leading to a decrease in the system's overall energy. For example, when a battery discharges, it converts stored chemical energy into electrical energy, but some energy is lost as heat. In physical systems, fizzling can be observed in various contexts, such as in mechanical systems where friction causes energy loss. This energy dissipation can affect the efficiency of machines and devices, making it an important consideration in engineering and design.
