The result is that one kilo of water occupies the volume of one liter. Water itself does not have a defined form, for that reason it takes the shape of the container that holds it. Thus, at a temperature of 0 C, freezing takes place, and water converts to ice. Conversely, at a temperature of 100 C, the liquid transforms into steam, this process is called boiling. Just like air, water has a force with which it pushes, this is called pressure .
Water is the medium where almost all substances dissolve and many chemical reactions take place.
Among these substances, many of them are so-called toxic and dangerous, which come from solid, liquid, and gas wastes produced by man. Depending on the temperature and the pressure, water changes easily from one state to another. It can appear as a liquid that flows, or a gas that rises into the atmosphere and forms clouds, or as solid to skate on. Water in its liquid state is very abundant on our plant. You will find it in the seas, lakes, and rivers, serving as home to plants, animals, and other organisms.
