bonjour

j'ai un dm en méthodes et pratiques scientifiques

en fait c'est un TP sur le microscopes, je voudrais juste savoir pourquoi les bouchons de liège (fait d'écorce d'arbre) convenaient-ils si bien pour conserver l'air d'une bouteille? en fait c'est une des nombreuses questions que Robert HOOKE cherchait à résoudre.
donc si quelqu'un pouvait m'aider se serait gentil parce que je doit le rendre pour lundi meri d'avance
