Endothermic and Exothermic Reactions and their Differences

Here is how you would classify the phase changes as endothermic or exothermic: melting, evaporation and sublimation are endothermic processes while freezing, condensation and deposition are exothermic processes. When moving from a more ordered state to a less ordered state, energy input is required. See more There are three primary phases of matter: solid, liquid and gas. A solid becoming liquid is called melting or fusion. A solid becoming gaseous is called sublimation. A liquid becoming solid is called freezing. A liquid changing to … See more Endothermic phase changes take in heat from the surrounding environment; they include melting, sublimation and boiling. The forces that bind together the atoms and molecules of a given substance determine its melting … See more In addition to temperature, pressure also affects melting and boiling; high pressures drive phase change temperatures up, low pressures reduce them. This is why water boils at 100 degrees … See more An exothermic phase change releases heat energy into its environment. These changes include freezing and condensation.
