Water is the most abundant molecule on Earth’s surface. It is essential for life on Earth. The unique properties of water makes life possible on earth. One property of water is surface tension. Water has a surface tension 2 – 4 times the surface tension of most organic liquids. Surface tension is highest for pure water. This enables insects called neuston to walk and live on the surface of water in low-nutrient water bodies‚ where they would starve if immersed in the water. This anomaly permits

Engineering materials Choice of materials for a machine element depends very much on its properties‚ cost‚ availability and such other factors. It is therefore important to have some idea of the common engineering materials and their properties before learning the details of design procedure. Common engineering materials are normally classified as metals and nonmetals. Metals may conveniently be divided into ferrous and non-ferrous metals. Important ferrous metals for the present purpose

applied magnetic field (spin glassbehavior and antiferromagnetism). Substances that are negligibly affected by magnetic fields are known as non-magnetic substances. They includecopper‚ aluminium‚ gases‚ and plastic. Pure oxygen exhibits magnetic properties when cooled to a liquid state. The magnetic state (or phase) of a material depends on temperature (and other variables such as pressure and the applied magnetic field) so that a material may exhibit more than one form of magnetism depending on
