(20 13? As shown in the figure, ABC, a right-angled thin glass tube with uniform inner diameter, has openings at both ends, with the section AB vertical and the section BC horizontal, with AB= 100cm and BC=40c. According to the analysis of the meaning of the question, after the A end is inserted into the mercury tank, the liquid column moves to the right 10cm.

Initial state: T 1=330k, V2= 1 10S?

Final state: V2= 130S.

Isobaric changes occur in the body, which can be obtained from Grusack's law:

V 1T 1=V2T2

Substitution solution, t2 = V2V1=130s110s× 330k = 390k.

A: When the temperature rises to 390K, the mercury column just overflows completely.
