When the vapours catch fire they burn to give heat and light in the form of a flame. During burning the vapours are converted into carbon dioxide and steam hence, burning of kerosene is a chemical change. In this way when we light a kerosene stove, both physical and chemical changes take place.
Kerosene consists of hydrocarbons. So when it exposed to heat or fire it gets sufficient amount of activation energy to reacts with oxygen present in atmosphere to form more stable Carbon dioxide and water with a large amount of heat (since the reaction is exothermic) and again the heat released, will continue this reaction.
