Physical state of matter
All matter, at least in principle, can exist in three forms: solid, liquid and gaseous. Solid Subtancat are rigid bodies with fixed form. Liquids are fluid and keep the form in the container in which they live. The gases also are fluid, but unlike liquids they have not given volume. The three states of matter can be transformed into one another without changing the composition of the substance. During heating, solid substances (eg ice) melt by formally created fluid (water). (Temperature at which this transition occurs is called the melting temperature). With further heating the liquid will turn into gas (this conversion is called the boiling temperature of the fluid). On the other hand, by cooling a gas that will be condensed being turned into juice. If Iëngu further cooled and passes it freezes solid state. In presented the three forms of water if the water properties are unique among common substances because the molecules have emphasized the solid in liquid are more crowded than those in the solid state.
