It is a definition for when a chemical reaction occurs and the temperature increases.
an exothermic reaction or and enothermic reaction
our body create it's own heat. That makes us Enothermic.
Rusting is an eXothermic reaction, not an eNDothermic.
Yeah, endothermic means that the heat is basically sucked out of it... or released while in an exothermic reaction, the heat is gathered or taken in. Take for example hot gas in a glass container: if it is cooled down of placed into a tub of ice, the gas will condense and the gas forms into droplets of liquid on the sides of the container and then drops to the bottom once there's enough of it.
