WebWhen considering whether a reaction is endothermic or exothermic, it is vital to separate the reaction system from the environment. What matters is the change in temperature of the system, not how hot or cold the system is in general. If the system cools down, that means heat is being released, and the reaction taking place is an exothermic ... WebExo - means “out” and endo - means “in.” Based on the words, it would make perfect sense if exothermic meant “thermal energy out” and endothermic meant “thermal energy in.”. However, there are many categories of energy, like light and sound, that can be involved in reactions. So, exothermic means “energy of any kind out” and ...
