What is the difference between endothermic and exothermic?
The difference between endothermic and exothermic energy is that exothermic energy is the reaction that releases energy and endothermic is the reaction in ehich energy is absorbed.
The difference between Endothermic and Exothermic energy is that Exothermic energy is the reaction that RELEASES energy, and Endothermic is the reaction in which energy is ABSORBED. Remember it by using the 'Ex' at the starting of Exothermic as 'Exit', because the meaning of exit is to leave or release. And the 'Endo' at the start of Endothermic kinda sounds like 'Indoor' so just remember it by saying indoor is INSIDE (another way to say…
Endothermic means (of a chemical reaction or compound) occurring or formed with absorption of heat. A.K.A. Melting. While exothermic means (of a chemical reaction or compound) occurring or formed with the liberation of heat. Or the releasing of heat. A.K.A. Freezing. So the difference is that endothermic is the absorbing of heat or melting, when exothermic is the releasing of heat or freezing.
Exothermic (hyperthermic) reaction: a chemical reaction that releases energy,* Endothermic (hypothermic) reaction: a chemical reaction that absorbs energy.* * Energy = heat, light, etc. The direction of Heat transfer: Exothermic reactions transfer heat energy to the environment. Endothermic reactions transfer heat energy from the environment .
Endothermic reactions and exothermic reactions all involve something called an enthalpy change: a change in the amount of energy a chemical contains. The difference here is that exothermic reactions release heat energy to their surroundings, whereas endothermic reactions absorb heat from their surroundings (in effect, getting colder).
Any reaction categories into exothermic and endothermic based upon change in enthalpy of reaction. If difference in enthalpy of product and reactant comes positive value then it is termed as endothermic and if it is negative value then exothermic reaction. Usually, vaporisation is considered as exothermic due to release in energy.
