Freezing is exothermic or endothermic
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 gas is called boiling or evaporation. A gas changing into a solid is called deposition, and … 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 An exothermic phase change releases heat energy into its environment. These changes include freezing and condensation. When a substance loses heat energy, the … See more In addition to temperature, pressure also affects melting and boiling; high pressures drive phase change temperatures up, low pressures reduce them.
