DefinitionAlthough the State is widely used in the physical sciences, but it is not easy to give a definition for accurate. Before we can give a general definition. Let's look at an example about the State before a couple of examples. Example: solid state, liquid and gas, water (H2O) consists of two hydrogen atoms, which consist of molecules to stick with one atom of oxygen in the Middle at room temperature. Water molecules are closer together and attracted mild interaction without adjacent islands. Makes each molecule moving relative each other like sand in an hourglass. The behavior of water molecules that cannot see this emerge, we see a physical properties of water in the liquid state, which we are familiar, because water molecules are not included into the rigid structure. The shape of water, so it is not a fixed and flow according to the container, and because the water molecules are very close together so there is water resistance to compression. Balloon compression observed from water containers, which do not have easy to squeeze a balloon containing air.
