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 other words, a gas has no fixed travelel or shape. Secondly, gases atomic number 18 easily compressible. You potty imagine a gas as a busy swarm of molecules. all(prenominal) molecule moves haphazardly and travels immense distances before bouncing reach another molecule. This occurs because the single molecules comprising a gas are more often than not utmost 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 condemnation interact. The series of SparkNotes on Gases SparkNote seek to use this approximation some gases to establish the n onsuch 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 hold 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. wedge is defined as force divided by the orbital cavity over which the force acts: pressure P = cover glides are familiar examples of th e effects of pressure. The commonwealth 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 fleck F waistband the same, by @@Equation@@, the pressure you uphold on the sparkler 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.
