Question

-A team wants to understand the effects of molecular weight on boiling point. The team has access to five substances with different molecular weights and the time to measure 50 boiling points. How can the team make the best use of the laboratory testing time? (1 point)

• by taking 10 measurements of each of the five liquids and finding an average
• by taking 10 measurements of each of the five liquids and using the highest value from each set
• by taking one measurement of each liquid and then working to improve the least certain liquid in the group
• by taking measurements of the liquids one at a time, making sure that the correct results are achieved before moving on to another liquid

Answer 1

The team can make the best use of the laboratory testing time by taking one measurement of each liquid and then working to improve the least certain liquid in the group. This approach allows the team to gather initial data on all the substances, and then focus on improving the accuracy or precision of the measurements for the substance that has the highest degree of uncertainty. This way, the team allocates its resources efficiently by prioritizing the substance that requires the most attention.
