Read MoreThe different properties of water allow it to be labeled as one of the most important substances to life on the planet, and much of it has to do with its chemical structure. For instance, the way the hydrogen and oxygen are bonded allows the molecule to dissolve different substances.
Read MoreThe main physical difference between the two is that one can be reused time and again, and the other cannot. When thermoplastics are heated, there is no chemical bonding and the material's physical properties remain unaffected. Thermoplastics then, can be molded, melted, and remolded repeatedly into various shapes, sizes, and objects.
Read MoreIt is even possible to "float" a steel needle on top of a glass of water if you place it gently, without breaking the surface tension (Figure 5). These cohesive forces are also related to the water's property of adhesion, or the attraction between water molecules and other molecules.
Read Moreflotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water.The flotation process was developed on a commercial scale early in the 20th century to remove very fine mineral particles that formerly had gone to waste in gravity concentration plants.
