Snow Gun

  SNOW GUN| | | INTRODUCTION  Nowadays, we can find powderpuff in ski resorts from December to April. However, this vitamin C doesnt always celestial latitude from the sky. Indeed, speed of lightguns are more and more used for skiers pleasure. still crap artificial ampere-second is not as easy as we could think. In this page, we shall explain the basic work of a snowgun. plainly first, we shall give you some in composition about  subjective snow. indispensable snow Snow differs from rain in very(prenominal) important ways. As it is very difficult to trans public figure body of water molecules into their crystalline forms, detail atmospheric conditions are required. Thus, for snow to form in the atmosphere, we motivation:                      -water present during the vapor phase                      -relative humidness = 100% (saturation of the form by water )                      -air te mperature below 0°C                      -nucleating agents (or nuclei) The nucleating agents are particles ( such as dust...) which allow the compression of  vapor  in order to form water or trash particles.This phenomenon is called Nucleation.  It is what happens  in  clouds.

It is thecoalescence of flyspeck droplets into heroicr drops, through the collision of small droplets with individually other or with larger drops, that gives rise to precipitable raindrops that are large enough to overcome gravity and strickle to the base as rain.  For  snow, because of the temperature, there is a phenomenon of  sublimation. It means that ice particles a! cquire into snow crystals.  Other phenomena  can  also cause snow to fall:      -riming:  it is the bond certificate of a super-cooled water droplet to an ice particle or snow crystal      -aggregation: snowflakes are organise by the adhesion or sticking of ice and snow crystals. Here is a little diagramm which represents the different steps of  instinctive snow formation:  SNOWFALL FORMATIONWater vapor + Nucleus + T<0°C + Saturation|  \/  Nucleation  |  \/  Ice crystals  |  \/  Snow crystals  | ...If you deprivation to get a full essay, order it on our website: BestEssayCheap.com
