QIC S A liquid with a coef- ficient of volume expansion of B just fills a spherical flask of volume V, at temperature T; (Fig. P10.61). The flask is made Ah of a material that has a coef- ficient of linear expansion of a. The liquid is free to expand into a capillary of cross-sectional area A at the top. (a) Show that if the temperature increases by AT, the liquid rises in the capil- lary by the amount Ah = (Vo/A) (B - 3a)AT. (b) For a typi- cal system, such as a mercury thermometer, why is it a good approximation to neglect the expansion of the flask? T; + AT T; Figure P10.61
