Usually find it in just a few forms. As of 1995, scientists have identified five states of matter. They may discover one more by the time you get old. You should know about solids, liquids, gases, plasmas, and a new one called Bose-Einstein condensates. The first four have been around a long time. The scientists who worked with the Bose-Einstein condensate received a Nobel Prize for their work in 1995. But what makes a state of matter? It& ,s about the physical state of molecules and atoms..) as

Home just needs a little spit and polish, rather than a complete overhaul. And that is the most common mistake new couples make. They dump all of their money into fixing a room or two—often the kitchen or the master bathroom—and they forget to work with what they have.Where to start? Put away your wallet and pick up your paint can. That’s right! Instead of replacing the kitchen, spruce it up a bit. Paint the walls, sand and stain the cabinets and put in a cheap floor, preferably linoleum.

A simple example of the spontaneous behavior of elements is the reaction of hydrogen gas with oxygen. Hydrogen atoms have such a great inherent tendency to form strong bonds with oxygen to yield water that a small energy of activation, in the
