Question

the passage below describes a process of scientific inquiry. select the part of the passage that describes drawing a conclusion. alvin was helping his mom make pickles. as he was adding salt to water to make brine, he recalled that sugar dissolves better in hot water than in cold. alvin thought that the temperature of the water might also affect how well salt would dissolve. to test this idea, alvin filled nine identical glasses with equal volumes of water. he filled three with water that was heated on the stovetop, three with water at room temperature, and the remaining three with chilled water. then he added a tablespoon of salt to each glass and stirred the water. alvin continued to add one tablespoon at a time to each glass until the salt no longer dissolved. he calculated the average amount of dissolved salt for each group. he found that the glasses containing chilled water dissolved the least amount of salt, and the glasses containing hot water dissolved the most. he concluded that the temperature of the water does indeed affect the solubility of salt. he asked his mom why this was the case, and she explained that the warmer water molecules move faster, which helps them break apart the salt crystals.

Explanation:

The process of scientific inquiry has steps like observation, hypothesis - formation, experimentation, analysis, and conclusion - drawing. In the passage, Alvin's statement "He concluded that the temperature of the water does indeed affect the solubility of salt" is where he draws a conclusion based on his experiment results.

Answer:

He concluded that the temperature of the water does indeed affect the solubility of salt.
