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 impromptu expand to fill the container they occupy, no matter its size. In former(a) words, a gas has no fixed assoilel or shape. Secondly, gases atomic number 18 easily compressible. You nominate imagine a gas as a busy swarm of molecules. all(prenominal) molecule moves haphazardly and travels swell distances before bouncing reach another molecule. This occurs because the single molecules comprising a gas are more often than not furthest apart. In fact, for a gas at pitiable closet, we can approximate that aside from a few random collisions, individual gas molecules do not interact. This approximation is what separates gases from solids and liquids, whose molecules of all plot of ground interact. The series of SparkNotes on Gases SparkNote seek to use this approximation just about gases t o establish the standard gas law and the kinetic molecular(a) theory. The ideal gas law macroscopically describes how gases behave under approximately 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. force per unit landing field is defined as force divided by the orbital cavity over which the force acts: pressure P = crank r ink glides are familiar examples of the eff! ects of pressure. The area of the blades of a skate 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 while F waistband the same, by @@Equation@@, the pressure you work out on the ice 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.
