Chemical reaction that takes in heat is known as endothermic reaction

Chemical reaction that releases heat is known as exothermic reaction

The most reactive elements and compounds may ignite spontaneously or explosively. They generally burn in water as well as the oxygen in the air. Reactivity is dependent upon temperature.

Solid- material in which atoms are tightly packed
Liquid- material in which atoms are not packed as tightly as solids
Gas- material in which atoms are loosely packed
