Is boiling water exothermic
Web29 dec. 2024 · The bond breaking is always endothermic. The formation of new bonds is exothermic, so depending on whether the old bonds or the new bonds were stronger, the reaction overall can be either endothermic or exothermic. When somebody says chemical bonds “contain potential energy” it is a HIGHLY misleading statement.

Web27 feb. 2024 · Boiling water is an example of an exothermic reaction, meaning it gives off energy in the form of heat. When water molecules reach their boiling point, they convert from a liquid to a gas, releasing heat energy into the surrounding environment. This heat energy is what we experience when we put our hand near boiling water. WebAnswer (1 of 3): Condensation is exothermic since the material you are starting with, a gas, (presumably water vapour (steam) in this case), must lose energy so that the molecules are moving slow enough for the hydrogen bonds to form between them so that water may be formed. Process is called con...
