Any action - chemical, physical, electrical or atomic - that gives off heat energy is exothermic. A few examples are a light bulb, a campfire, your computer CPU (when in use) and rubbing two sticks together. "Exo" and "thermic" are both combined forms from early Greek, the one meaning "out" or "outward", the other meaning "heat". The opposite is "endothermic", "endo" meaning "in" or "inward".

ViviExothermic reactions release heat energy to the surroundings. Examples include combustion reactions, neutralization reactions, and many organic chemical reactions. When bonds are formed in the products of a reaction with stronger bonds than those in the reactants, excess energy is released in the form of heat.

If it get cold exothermic or endothermic?
Exothermic phenomenon
Is the reaction between HF and NaOH an endothermic or exothermic reaction?
EXTREMELY!!!!! exothermic. As in fires and explosions exothermic.
Is ionization endothermic or exothermic?
It is exothermic. Take for example H2SO4 H2SO4 -> H+ + HSO4- This is very exothermic
Is drain cleaner endothermic or exothermic?
Drain cleaner is typically exothermic. When it is mixed with water, it produces heat as a result of an exothermic chemical reaction. This heat helps to dissolve and remove the clogs in the drain.
A reaction that releases energy as it occurs is classified as?
A reaction that releases energy is exothermic.
