Salut jeune @Antoinee , dans ce QCM on te dis que la pression osmotique est de 1140mmHg. Or nous savons que 760mmHg = 1 atm, donc si tu fais 1140 / 760 tu tombe sur 1.5 atm.

Ensuite tu sais que : (delta T a) = Pi / 12.

Item A : Pi étant la pression osmotique, cela nous donne 1.5/12 = 0.125

 

Item B : Pour un (delta T a 37°) nous avons 1.5/13.6 = 0.110

 

j’espère avoir été clair 😉
