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.
Temperature Effects on Phase. If pressure is constant, the state of a substance will depend entirely on the temperature it is exposed to. For this reason, ice melts if taken out of a freezer and water boils out of a pot if left at too high a temperature for too long.he point at which matter subjected to a particular temperature under conditions of constant pressure begins to change its phase is called the phase change threshold. At this temperature, every bit of the substance exposed to the heat will change its state.
