CAS 7732-18-5
:Eau
Description :
Eau, avec la formule chimique H₂O et le numéro CAS 7732-18-5, est une substance vitale et omniprésente sur Terre. C'est une molécule polaire, caractérisée par sa forme angulaire, ce qui entraîne un moment dipolaire significatif. Cette polarité contribue à ses excellentes propriétés de solvant, lui permettant de dissoudre une large gamme de substances ioniques et polaires. Eau a une capacité calorifique spécifique élevée, ce qui lui permet d'absorber et de retenir la chaleur, jouant un rôle crucial dans la régulation des températures dans les environnements naturels. Elle présente des propriétés uniques telles qu'une haute tension superficielle et une cohésion, qui sont essentielles pour divers processus biologiques. Eau existe sous trois états : solide (glace), liquide et gaz (vapeur de Eau), avec ses transitions de phase se produisant à des conditions spécifiques de température et de pression. De plus, Eau a une chaleur latente de vaporisation élevée, ce qui est important pour des processus tels que le refroidissement et la régulation climatique. Sa densité est maximale à 4°C, ce qui fait que la glace flotte sur le Eau liquide, une caractéristique essentielle pour les écosystèmes aquatiques. Dans l'ensemble, Eau est fondamental pour la vie, influençant les réactions chimiques, les fonctions biologiques et les systèmes environnementaux.
