Question

review the lab report conclusion and then answer the question.
based on the data gathered, we measured the boiling point of water as 99.51 degrees celsius. the error against the expected measurement was 0.49 percent. sources of error may have been impurities in the water, contamination of the equipment, or human error in reading the thermometer. if we repeated the experiment, we might achieve more accurate results by sterilizing our equipment, using distilled water, and verifying that the thermometers readings are correct.
what is the texts main purpose?
to record an experiment and demonstrate learning
to suggest that accurately reading a thermometer is an important skill
to convince readers that the boiling point of water is 99.51 degrees celsius
to inform readers about water impurities

Explanation:

The text is a lab report conclusion that presents experimental data (measured boiling point of water, error percentage), identifies sources of error, and suggests improvements for future experiments. Its core goal is to document the experiment’s outcomes and reflect on the process to show understanding.

Answer:

to record an experiment and demonstrate learning
