The longer you look in the past the more you understand your situation much like the mirror while you’re driving. Without either you’d be lost. And Finally just like looking into the past‚ it’s a neccessary effort that

States of matter Four fundamental states: Solid - In a solid the particles (ions‚ atoms or molecules) are packed closely together. As a result‚ a solid has a stable‚ definite shape‚ and a definite volume. Solids can only change their shape by force‚ as when broken or cut. Liquid - A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. The volume is definite if the temperature and pressure are constant

Analysis Questions: Cycles of Matter 1. Explain the role of decomposing bacteria in the carbon and nitrogen cycles. In the carbon cycle‚ decomposing bacteria release carbon from the decaying bodies or waste into the atmosphere. Without them‚ it won’t be able for any organism to access the carbon stored in dead bodies. In the nitrogen cycle‚ decomposing bacteria breaks down animal waste‚ which creates ammonia and nitrate products rich in nitrogen. Although no animals or plants cannot directly

The Structure of Matter There is a large overlap of the world of static electricity and the everyday world that you experience. Clothes tumble in the dryer and cling together. You walk across the carpeting to exit a room and receive a door knob shock. You pull a wool sweater off at the end of the day and see sparks of electricity. During the dryness of winter‚ you step out of your car and receive a car door shock as you try to close the door. Sparks of electricity are seen as you pull a wool blanket

States of matter are the distinct forms that different phases of matter take on. Historically‚ the distinction is made based on qualitative differences in bulk properties. Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter maintains a fixed volume but adapts to the shape of its container; and gas is the state in which matter expands to occupy whatever volume is available. This diagram shows the nomenclature for the different phase transitions

Nicholas G. Carr published this article in the May of 2003. Its purpose was to convey to the reader that IT no longer matters and may no longer be relevant. Carr’s reasoning behind this is that corporations have universally accepted and use IT; this makes the use of IT a commodity and no longer puts the corporation at an advantage over any other using IT. Which means that using IT would no longer be a strategic decision for the corporation. After explaining this Carr offered new rules for IT management
