Liquid is one of the principal states of matter. A liquid is a fluid that has the particles loose and can freely form a distinct surface at the boundaries of its bulk material. The surface is a free surface where the liquid is not constrained by a container. [1]A liquid's shape is confined to, not determined by, the container it fills. That is to say, liquid particles (normally molecules or clusters of molecules) are free to move about the volume, but they form a discrete surface that may not necessarily be the same as the vessel. The same cannot be said about a gas; it can also be considered a fluid, but it must conform to the shape of the container entirely. At a temperature below the boiling point, a liquid will evaporate until, if in a closed container, the concentration of the vapors belonging to the liquid reach an equilibrium partial pressure in the gas. Therefore no liquid can exist permanently in a complete vacuum. The surface of the liquid behaves as an elastic membrane in which surface tension appears, allowing the formation of drops and bubbles. Capillarity is another consequence of surface tension. Only liquids can display immiscibility. The most familiar mixture of two immiscible liquids in everyday life is the vegetable oil and water in Italian salad dressing. A familiar set of miscible liquids is water and alcohol. Only liquids display wetting properties. Liquids at their respective boiling point change to gases (except when superheating occurs), and at their freezing points, change to solids (except when supercooling occurs). Even below the boiling point liquid evaporates on the surface. Objects immersed in liquids are subject to the phenomenon of buoyancy, which is also observed in other fluids, but is especially strong in liquids due to their high density. Liquid components in a mixture can often be separated from one another via fractional distillation. The volume of a quantity of liquid is fixed by its temperature and pressure. Unless this volume exactly matches the volume of the container, a surface is observed. Liquids in a gravitational field, like all fluids, exert pressure on the sides of a container as well as on anything within the liquid itself. This pressure is transmitted in all directions and increases with depth. In the study of fluid dynamics, liquids are often treated as incompressible, especially when studying incompressible flow.

3. Laser Welding and all about Laser Welding
October 10, 2008
Laser Welding is also called Laser Beam Welding and it is a commercial process and is used when you want to fuse together several pieces of metal. The way it works is that a laser beam is pointed to a joint and then the beam is moved along that joint. The process will melt the metals into a liquid, fuse them together, and then make them solid again.
This is generally a process that is used when you want a linear continuous seam or at times when you want spot welds in a certain area. There are basically two types of laser welding. Laser conduction welding focuses the beam on a specific are... (read more)

9. The Fact You Do Not Know About Reverse Osmosis Water
October 10, 2008
RO water basically mean water produced by the process of Reverse Osmosis. Osmosis in science basically is the process where 2 types of liquid being separated by a membrane, the specific molecule from four solvent will move from a higher saturation to a lower four until 2 sides reach the same saturation level, by the law of nature. So, the key term here is membrane (or filter) and the direction of the flow. By allowing only certain type of molecule (mainly water or H2O are of smaller size) to pass through in term of size and reverse the osmosis flow direction. So this can only be done by fo...

Float - or window - glass has what is called a ‘tin’ or ‘tinned’ side and an ‘air’ side. This refers to the modern method of making sheet glass. Molton glass is floated on to a pool of liquid tin, where gravity and surface tension do their job to smooth and polish the sheets of glass.
It is the side touching the tin – the ‘tinned’ side - that you want to avoid when using glass paint, you want to paint on the ‘air’ side. The residue of oxides left on the ‘tin’ side is likely to adversely affect the colours of your stained glass paint... (read more)

15. What Are Antioxidants, Really?
October 07, 2008
The term antioxidant has been tossed around more and more lately and we'd like to know what it really means. What is so wrong with oxidants that we have to be so against them? One definition for antioxidant is any substance that reduces oxidative damage (damage due to oxygen) such as that caused by free radicals. Free radicals? Like Libertarians or something? So it's still not quite clear - hopefully we can make it a little clearer.
What happens is that your body creates a molecule called a "free radical" as a natural by-product of oxygen use. A free radical is an oxygen molecule ... (read more)
