Question

Instructions: Alice and Sunil, two students, were provided with two test tubes, each containing distinct quantities of transparent, colorless liquids. Using identical burners, they heated the liquids in the test tubes. The temperatures of the liquids were recorded at consistent time intervals, and the outcomes were graphically represented below. These experiments were conducted at sea level. Refer to the accompanying graphs to address any subsequent questions.





Which of the students might have utilized pure water in one of their test tubes?

Answer 1

To determine which student might have utilized pure water in one of their test tubes, we would need to analyze the temperature vs. time graphs that display the heating behavior of the liquids.

Pure water has a characteristic boiling point of 100°C at sea level, and it will show a specific pattern on the temperature graph as it is heated. The temperature will rise steadily until it reaches 100°C, at which point it will plateau while it is boiling, before rising again if heated past the boiling point.

If one of the graphs displays this plateau at around 100°C, then that student could be using pure water.

However, since I cannot view the graphs directly, I'm unable to make a definitive conclusion. Based on the options, you should select:

- If one of the graphs shows the characteristic boiling behavior of water, select the corresponding student.
- If neither graph displays the behavior expected from pure water, then the answer would be "neither Alice nor Sunil."

Please review the graphs for the boiling point behavior to make the correct choice.
