A volumetric flask made of Pyrex is calibrated at 20.0C. It is filled to the 100-mL mark with 35.0C acetone. After the flask is filled, the acetone cools and the flask warms so that the combination of acetone and flask reaches a uniform temperature of 32.0C. The combination is then cooled back to 20.0C. (a) What is the volume of the acetone when it cools to 20.0C? (b) At the temperature of 32.0C, does the level of acetone lie above or below the 100-mL mark on the flask? Explain.
