A glass bottle is filled with salted water, and a pipette is inserted in the top through the cork. ( Leaving the bottle sealed). A thermometer is also inserted to keep record of the temperature. The glass bottle is then inserted in ice until the water reaches Zero Celsius. Finaly, the temperature and the rise of the water in the pipette was observed. A graph V(cm^3) vs T(C) was also created. In this process, did the expansion of the plastic pipette and the glass(regular) affect the data of the rise and fall of the water in the pipette . Explain. I have that the expansion in the plastic pipette would indeed affect the data, because that is what the reading of the water is done through. And therefore, say the water would have risen 3cm's but because the expansion of the plastic it only rose 2.5cm, then the height would be smaller, also the cross sectional area would be larger, and so the V(cm^3) would be different. Since,Change in V= Change in h X A . I think that is correct. However when it comes to glass , I can't see how it would affect it because even if the bottle expands and water does not go as high in the bottle, it still rises in the pipette the same height. But I am unsure of this because it seems to me like it should affect it somehow, but how?
