This typically occurs when water vapor molecules come.

Is converting frost to water vapor endothermic or exothermic. Melting, evaporation and sublimation are endothermic processes while freezing, condensation. An exothermic reaction gives off heat energy. Heat is evolved, partly in consequence of the chemical combination and partly from the condensation of the gas to the.

Exothermic and endothermic reactions both cause some type of energy level differences. Examples of this would be melting ice cubes, conversion of frost to water vapor, and baking bread. In an exothermic reaction, energy is released in the form of heat.

The applied heat helps break the intermolecular bonds between the water molecules, which spreads in the molecules further. Here is how you would classify the phase changes as endothermic or exothermic: Therefore, boiling water is an endothermic process.

One mole is equal to 6.02214076×10 23 molecules, or. Thus dissolution of a gas in water is an exothermic process.
