Concentration.
Combustion or burning is the sequence of exothermic chemical reactions between a fuel and an oxidant accompanied by the production of heat and conversion of chemical species.
Many elements have this property, including all the alkali metals and the heavier alkaline earth metals. Also, many compounds such as sulfuric acid have exothermic heats of solution, but solution is not technically a "reaction."

Exothermic reactions give off heat.
Its a physical property as it is not involved with chemical reactions.
Decomposition reactions always have one complex reactant and two or more simpler products.
Evaporation of a liquid, which is an endothermic process.
Temperature is an intensive physical property.
there are alot of chemical mixtures that create exothermic REACTIONS, but no chemical in particular. my favorite chemical reaction is thermite. (alluminum powder, iron(ii) oxide) temperatures reach 9000 degrees!
Because it is its property to release heat when it reacts with water.
Physical properties are it's rest quantitative properties, while the chemical properties are its reactions to things like temperature and other substances. I hope somebody gives you a more comprehensive answer. :)
