Question

the passage below describes a process of scientific inquiry. select the part of the passage that describes analyzing the data.
sprinkling salt on an icy driveway
britney watched her dad sprinkle salt on their driveway before a big snowstorm. she had learned that table salt, or nacl, prevents ice formation by splitting into two particles and lowering the freezing point of water. she had also heard that calcium chloride, or cacl₂, is an even better deicer. she wondered if this might be because cacl₂ splits into three particles instead of two. britney predicted that the more particles a substance split into when dissolved, the better it would work as a deicer. she filled six cups with equal volumes of water. she dissolved sugar, which stays as one particle, in the first two cups. she dissolved nacl in the next two cups and cacl₂ in the remaining cups. each solution had the same concentration. she then left the cups outside in the snowstorm overnight. she found that the cups of sugar solution had the most ice in them and the cups of cacl₂ solution had the least. she decided that she was correct in predicting that substances that break into more particles make better deicers. she shared the results with her chemistry teacher, and he confirmed that a substances ability to change waters freezing point is impacted by how many particles it breaks into.

Explanation:

In the scientific inquiry process, after conducting an experiment (leaving solutions outside in snow - storm), Britney analyzed the data by observing the amount of ice in each cup (sugar solution had most ice, CaCl₂ solution had least). Then she made a conclusion based on this data analysis about the relationship between the number of particles a substance splits into and its de - icing ability.

Answer:

She found that the cups of sugar solution had the most ice in them and the cups of CaCl₂ solution had the least. She decided that she was correct in predicting that substances that break into more particles make better deicers.
