Change of Phase. Matters can be in four states like solid, liquid, gas and plasma. Distance between the molecules or atoms of the matter shows its state or phase. Temperature and pressure are the only factors that affect the phases of matter.his is a phase of change of water from solid to liquid. As you can see at the beginning ice is at -15 ÂºC, we give heat and its temperature becomes 0 ÂºC which is the melting point of ice. During melting process temperature of the ice-water mixture does not change.
A phase is a distinctive form of a substance, and matter can change among the phases. It may take extreme temperature, pressure or energy, but all matter can be changed. There are six distinct changes of phase which happens to different substances at different temperatures. The six changes are: Freezing: the substance changes from a liquid to a solid. Melting: the substance changes back from the solid to the liquid. Condensation: the substance changes from a gas to a liquid.
