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

The best way for the team to make use of the laboratory testing time would be to take 10 measurements of each of the five liquids and finding an average. This would provide a more representative and reliable result for each substance's boiling point.
