A student adds ice to several samples of water. The results are shown in the table.
Which conclusion can be drawn from the results?
(1 point)
As the temperature increases, the
• kinetic energy of the water molecules decreases.As the temperature decreases, the
• kinetic energy of the sample increases.
As the amount of ice added
• increases, the change in temperature increases.
As the amount of ice added
• decreases, the temperature decreases.

Answer 1

Based on the data provided in the table, we see that for each sample, when ice is added, the final temperature of the water decreases. This suggests that as the amount of ice increases, the temperature of the water decreases. Therefore, the most appropriate conclusion based on the results is:

As the amount of ice added increases, the change in temperature increases.

This conclusion aligns with the observation that more ice leads to a greater decrease in the final temperature of the water samples.
