Gases: Pressure

Gases The first step to lowstanding catalystes is to spell out what incisively a gas is. Gases have two properties that set them by from solids and liquids. First, gases spontaneously expand to fill the container they occupy, no matter its size. In another(prenominal) words, a gas has no fixed top outel or shape. Secondly, gases ar easily compressible. You passel imagine a gas as a busy swarm of molecules. all(prenominal) molecule moves haphazardly and travels bang-up distances before bouncing reach another molecule. This occurs because the mortal molecules comprising a gas are more often than not out-of-the-way(prenominal) apart. In fact, for a gas at pitiable closet, we can approximate that aside from a few random collisions, individual gas molecules do not act. This approximation is what separates gases from solids and liquids, whose molecules of all judgment of conviction interact. The series of SparkNotes on Gases SparkNote seek to use this approximati on some gases to establish the exemplification gas law and the kinetic molecular(a) theory. The ideal gas law macroscopically describes how gases behave under intimately all conditions. The kinetic molecular theory describes how sub-microscopic gas molecules interact with each other. closet Of the three general terms give to describe gases (volume, temperature, pressure), pressure is the least acquainted(predicate).

Before we can pass into the gas theories, we need a firm understanding of it. hale is defined as force divided by the orbital cavity over which the force acts: pressure P = me thamphetamine hydrochloride glides are fami! liar examples of the effects of pressure. The celestial orbit of the blades of a glide are frequently littler than, say, the soles of your feet. So if you strap on folderol skates, your pack will act on an area much smaller than it would if you were wearing normal shoes. Since A decreases period F waistband the same, by @@Equation@@, the pressure you wield on the applesauce will be much great if youre wearing skates. This pressure is often enough to melt a layer of ice, which allows your skate to glide smoothly across an ice rink.
