Chloe06 Posted December 13, 2018 Posted December 13, 2018 (edited) Bonjour, dans ce qcm d'annale, la réponse D est juste mais je ne comprend pas comment on arrive à ce résultat. D'après la formule, on a 1×8.5×(26.85+273) = 2550 pa 2550/100 000 = 0.0255 atm Merci d'avance ! Edited December 13, 2018 by Chloe06 Quote
