Is plasma exothermic or endothermic

Answer 1

Plasma itself is not classified as exothermic or endothermic; these terms describe the heat exchange during phase changes or chemical reactions. However, the process of ionizing a gas to create plasma is typically endothermic, as it requires energy input to strip electrons from atoms. Conversely, when plasma cools and recombines into a gas, it can release energy, making that process exothermic.
