Why do some reactions get hot?
Combustion releases energy to the surroundings; at constant pressure this is described by a negative enthalpy change.

Шта се заиста дешава?
Наука се лакше памти када се дефиниција повеже са нечим мерљивим или уочљивим.
At constant temperature and pressure, ΔG combines enthalpy and entropy to indicate thermodynamic spontaneity.

Chemical reactions rearrange bonds and redistribute energy. If the reacting system transfers energy to its surroundings as heat at constant pressure, its enthalpy change is negative.
