  rdf:value "Fluido atóxico, incoloro, insípido e inodoro, con un punto de ebullición de -196° C. Expuesto al aire, se evapora en la atmósfera con gran rapidez. Se utiliza principalmente como un criógeno (refrigerante). Puede producir quemaduras graves al tacto, por lo que se debe manipular con cuidado."@es, "Liquid nitrogen is a non-toxic, colorless, tasteless, odorless fluid with a boiling point of -196° C. On exposure to the air, it evaporates into the atmosphere quite rapidly. It is used mainly as a cryogen (refrigerant). It can cause severe burns on touch and must be handled safely."@en ;
