Selon le troisi\u00e8me principe de la thermodynamique:<\/strong><\/p>\n

L’entropie d’un syst\u00e8me se rapproche d’une valeur constante lorsque la temp\u00e9rature approche le z\u00e9ro absolu.<\/em><\/p>\n

Le z\u00e9ro absolu est la temp\u00e9rature th\u00e9orique la plus froide \u00e0 laquelle le mouvement thermique des atomes et des mol\u00e9cules atteint son minimum.\u00a0Il s’agit d’un \u00e9tat dans lequel l’enthalpie et l’entropie d’un gaz parfait refroidi atteint sa valeur minimale, prise \u00e9gale \u00e0 0.\u00a0Classiquement<\/strong>\u00a0, il s’agirait d’un \u00e9tat d’\u00a0immobilit\u00e9<\/strong>\u00a0, mais\u00a0l’<\/strong>\u00a0incertitude\u00a0quantique<\/strong>\u00a0impose que les particules poss\u00e8dent toujours une\u00a0\u00e9nergie du point z\u00e9ro finie<\/strong>\u00a0.\u00a0Le z\u00e9ro absolu<\/strong>\u00a0est not\u00e9 0 K sur l’\u00e9chelle Kelvin,\u00a0\u2212273,15 \u00b0 C<\/strong>\u00a0sur l’\u00e9chelle Celsius et\u00a0\u2212459,67 F<\/strong>\u00a0sur l’\u00e9chelle Fahrenheit.<\/p>\n<\/div>\n<\/div>\n
