Chemistry question #98
Q:Chez le roman "Cat's Cradle" par Kurt Vonnegut, Jr., il y a Glace-neuf appelé composé chimique. La Glace-neuf est une formule qui gèle n'importe quoi au-dessous de 114 degrés de centigrade. Ma question est : Est-ce qu'ou il y a a été quelque chose inventé/examiné qui ressemble à ce produit ?
la réponse
R:
Yes, in real life there is something called Ice-9. If you take water and subject it to about -120C and 3 atmospheres of pressure you get a crystalline state called Ice-IX, or Ice-9. But it's not like Vonnegut's Ice-nine. It can't do what Vonnegut's fictional stuff could. If you warm it up or reduce the pressure it just melts like ordinary ice. You can see a chart of all the states of solid water and even a note about Vonnegut at the Physics of Ice.
