WebFive Changes of State are: Melting. Freezing. Evaporation. Condensation. Sublimation. The process by which a substance changes from the solid phase to the liquid phase is known as melting. The process by which a … A disorder-broadened first-order transition occurs over a finite range of temperatures where the fraction of the low-temperature equilibrium phase grows from zero to one (100%) as the temperature is lowered. This continuous variation of the coexisting fractions with temperature raised interesting possibilities. On cooling, some liquids vitrify into a glass rather than transform to the equilibrium crystal phase. This happens if the cooling rate is faster than a critical cooling rat… iowa western ged classes
