Along with those questions o have a part c to question 2. It is How will the density of the acetone at the end of the two hours compare to its density when it was a liquid.

Work and/or explanations required for all items. 1) (a) Assuming a properly functioning and correctly used thermometer with a sensitivity of one "C, if it reads 63.4 C when it is placed in a beaker of liquid, which of the following are possible values for this particular measurement of the temperature of the liquid? Circle ALL that apply, and explain your reasoning. 63.5 . C 64.6 .C 63.9 .C 62.9 .C 63.1 .C 62.6 -C (b) If five measurements of the temperature of this liquid produced the following readings-65.5 .C, 65.1 .C, 65.8 .C, 65.6 "C, and 66.0 C-what one value would you report, including uncertainty, for this set of measurements? Explain. (c) Explain why knowing the precision of a set of measurements tells us nothing about the accuracy of the measurements. 2) Five hundred milliliters of a liquid called acetone is placed in a sealed transparent container. (a) You observe the container shortly after the acetone is poured in and then again in two hours when the container appears to be empty. What inference would you draw about what process the acetone underwent during the two hours? Explain. (b) What would you infer about the positions and motions of the acetone particles at the start and end of the two-hour period and why would you draw that inference
