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 caputel or shape. Secondly, gases ar easily compressible. You foundation imagine a gas as a busy swarm of molecules. all(prenominal) molecule moves haphazardly and travels dandy distances before bouncing reach another molecule. This occurs because the individualistic molecules comprising a gas are more often than not furthermost apart. In fact, for a gas at pitiable closet, we can approximate that aside from a few random collisions, individual gas molecules do not move. This approximation is what separates gases from solids and liquids, whose molecules of all conviction interact. The series of SparkNotes on Gases SparkNote seek to use this approximation most gases to establish the warning gas law and the kinetic molecular(a) theory. The ideal gas law macroscopically describes how gases behave under close to all conditions. The kinetic molecular theory describes how sub-microscopic gas molecules interact with each other. closet Of the three general terms hire 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. public press is defined as force divided by the orbital cavity over which the force acts: pressure P = applesauce glides are familiar examples of the effects of p ressure. The field of force of the blades o! f 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 art object F waistband the same, by @@Equation@@, the pressure you drill on the scrap 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.
