volumetric flask made of Pyrex glass is calibrated at 20 °C.It is filled to the 100 mL mark with 35 °C 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 °C. The combination is then cooled to 20 °C. a) What is the volume of the acetone when it is at 20 °C? b)At the temperature of 32 °C, does the level of acetone lie above or below the 100 mL mark?
