In thermodynamics, the word exothermic describes a process or reaction that releases energy in the form of heat. Its etymology stems from the Greek prefix exo-, meaning “outside” and the the Greek suffix –thermic, meaning “to heat”. The opposite of an exothermic process is an endothermic process.
The concept is frequently applied in physical sciences to e.g. chemical reactions, where chemical bond energy is converted to thermal energy (heat).

In thermodynamics, the word endothermic describes a process or reaction that absorbs energy in the form of heat. Its etymology stems from the Greek prefix endo-, meaning “inside” and the Greek suffix –thermic, meaning “to heat”.

Exothermic reactions release heat. Endothermic reactions absorb heat.

Exothermic reaction is a reaction whereby heat is released and endothermic reaction is one whereby heat is taken in. So exothermic and endothermic simply means release of heat and taking in heat respectively.

An exothermic reaction means that a chemical reaction releases energy like fire burning. AN endothermic reaction is aborbing engery like a cold pack. You break the packet and the chemicals come together and become colder.

* Exothermic- energy is being released (negative)
* Endothermic- energy is being taken up (positive)
Two characteristics of thermodynamics

Exotheremic Reactions are the reactions which release heat.
Endothermic Reactions are the reactions absorb heat.

Hi. "Exo" means outside and "Endo" means inside. One gives heat out, the other takes heat in.

"heat producing" and "heat consuming", respectively.
