reactivi

#1373

Într-un laborator de analize chimice se utilizează N reactivi. Se ştie că, pentru a evita accidentele sau deprecierea reactivilor, aceştia trebuie să fie stocaţi în condiţii de mediu speciale. Mai exact, pentru fiecare reactiv x, se precizează intervalul de temperatură [minx, maxx] în care trebuie să se încadreze temperatura de stocare a acestuia.
Reactivii vor fi plasaţi în frigidere. Orice frigider are un dispozitiv cu ajutorul căruia putem stabili temperatura (constantă) care va fi in interiorul acelui frigider (exprimată într-un număr întreg de grade Celsius).
