For example, frozen nitrogen will form both the liquid phase and the vapor phase when exposed to normal temperature and pressure. Melting is a physical process that results in the phase transition of a substance from a solid to a liquid. Multiple phase changes can occur at once. For example, if you view the sublimation of dry ice into carbon dioxide gas, the white vapor that is observed is mostly water that is condensing from water vapor in the air into fog droplets. The enthalpy change during melting or fusion is the latent heat. The latent heat of fusion of ice is 3.34 x 10 joules per kilograms (or, 3.34 x 10J/Kg). Phase changes aren't always clear when observing a situation. The latent heat of fusion or melting, of a solid, is the quantity of heat in joules required to transform a solid, at its melting point, to a liquid without any variation in temperature. Plasma most often forms from ionization of a gas, although if sufficient energy and enough space are available, it's presumably possible for a liquid or solid to ionize directly into a gas. Plasma: Plasma can recombine to form a gas. Gases form from the sublimation of solids, vaporization of liquids, and recombination of plasma. Gases: Gases can ionize into plasma, condense into liquids, or undergo deposition into solids. Liquids form by condensation of gases and melting of solids. Liquids: Liquids can vaporize into gases or freeze into solids. Solids form by deposition from gases or freezing of liquids. Water can be observed as a liquid, a solid (ice), or a gas (water vapour) and moves. Solid to a liquid is called Wiki User 21:56:24 Study now See answers (3) Best Answer Copy Going from a solid to a liquid is measued by a substance's Melting Point (MP), and is. Fluids have a definite mass and volume at a given temperature and pressure. Solids: Solids can melt into liquids or sublime into gases. Materials can be changed from one state to another by heating or cooling. The term Fluid consists of gases and liquids. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa. At the melting point the solid and liquid phase exist in equilibrium. Another way to list phase changes is by states of matter: The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid.
