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.
By lowering the temperature of water, it can freeze into a solid. By heating water, it can become steam which is a gas. Whether solid, liquid or gas &dash; water is still water. Pressure can change matter from one state to another. Deep in the earth solids turn to liquids because the heavy weight of layers and layers of the earth push down on the solids causing them to turn to liquid magma. This is just one example of how pressure can change matter too.
