Airplanes are very heavy, so the force required to balance gravity and keep them in the air must be large. The engines propel the airplane forward, but we need to understand what gives the upward push, or lift, necessary to keep the plane in the air. This lift comes from the shape of the wings, which are typically curved on the top and flat on the bottom. This design requires air to flow more rapidly over the top of the wings than over the bottom, which creates a lower air pressure above the wing than below.
Metals are often good conductors of An explosion is a dramatic example of a chemical reaction we can see with our naked eyes. Handy Chemistry 7/8/13 2:44 PM Page 43 What makes a rubber band stretchy? Rubber bands are made of long polymer molecules. These are all tangled together, and you could think of them as being similar to a bunch of interwoven springs. The polymers can be stretched to a more extended state, which is what allows a rubber band to stretch without breaking. More accessible configurations exist, however, when they are in a more contracted state, which means that the more contracted states have higher entropy (see “Physical and Theoretical Chemistry”) and for this reason are more favorable.
If the spin magnetic moments are oriented randomly, the object won’t be magnetic. The trick is that only certain materials have the potential to exhibit magnetism, and we’ll get to that next. What determines which metals can be magnetized? Chemists discuss magnetism in terms of three basic categories: diamagnetism, paramagnetism, and ferromagnetism. Diamagnetic materials have all of their electrons arranged in pairs, which, by definition, means that their spin magnetic moments must all be arranged in pairs and thus cancel each other out.
