Purpose: Introduce several common pieces of glassware and to illustrate why one piece of glassware maybe preferred for a particular measurement.

Post-Lab questions

Question 1. When taking a measurement, how do you determine the last digit in the number you report?

Question 2. When using a graduated cylinder, the liquid often curves up along the sides of the container. Where along this curve should you measure the volume?

Question 3. Explain why your measurement might not be identical to the measurements taken by your lab mates. Assuming all the measurements were taken correctly, what is the maximum number of digits that should differ between your measurement and those of your lab mates?

Question 4. When measuring a small volume, such as the volume of a small test tube, which size graduated cylinder should you use to obtain the most precise measurement. Explain your choice.

Question 5. Give an example when a beaker might be a good choice for determining a volume of a liquid.

Question 6. What would be a limitation when using the lab thermometer? Was the temperature of the ice water what you expected?

Question 7. What the advantages of using the metric system. Use the measurements made for length to support your answer.
