👉 Non-burning is a concept in chemistry and physics that refers to substances or compounds that do not undergo combustion, burning, or spontaneous combustion. It involves the presence of a catalyst or an additional substance in the system that prevents the reaction from occurring spontaneously. In more general terms, non-burning refers to substances that do not produce heat when they are heated. This is different from spontaneous combustion, which occurs when a fuel or reactant burns without any external intervention and produces significant heat as a byproduct
