Question

the passage below describes a process of scientific inquiry. select the part of the passage that describes drawing a conclusion. hint: to draw a conclusion, you decide if the data support or refute the hypothesis. sophia was getting ready to go for a hike. in order to stay hydrated, she dissolved an electrolyte tablet in a glass of water. as she waited for the tablet to fully dissolve, she wondered how she could speed up the reaction rate. sophia predicted that warmer water would cause electrolyte tablets to dissolve more quickly. she filled four cups with equal volumes of water. she warmed two of the cups in the microwave and left the other two cups at room temperature. she dropped one tablet into each cup at the same time and used a timer to track how long each tablet took to stop fizzing. she averaged the times from each group and noticed that the warmer water almost cut the fizz time in half! sophia concluded that the temperature of the water does affect the reaction rate of electrolyte tablets. she shared her results with her hiking group.

Explanation:

The process of scientific inquiry involves several steps. Drawing a conclusion is when one decides if the data supports or refutes the hypothesis. In the passage, Sophia's hypothesis was that warmer water would cause electrolyte tablets to dissolve more quickly. After conducting the experiment (filling cups, warming some, timing), she analyzed the data (averaged times, saw warmer water cut fizz time). Then she made a statement about the relationship between water temperature and reaction rate of electrolyte tablets. This statement is her conclusion as it directly relates the data (fizz time results) to the initial hypothesis (effect of water temperature on dissolution rate).

Answer:

Sophia concluded that the temperature of the water does affect the reaction rate of electrolyte tablets.
