(1 point)
Responses

As the temperature increases, the kinetic energy of the water molecules decreases.
As the temperature increases, the kinetic energy of the water molecules decreases.

As the amount of ice added decreases, the temperature decreases.
As the amount of ice added decreases, the temperature decreases.

As the temperature decreases, the kinetic energy of the sample increases.
As the temperature decreases, the kinetic energy of the sample increases.

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

Answer 1

To analyze the data presented in the table, we can look at the relationship between the amount of ice added and the final temperature decreases.

As more ice is added (in grams), we generally see a greater decrease in the final temperature from the initial temperature. Specifically:

• Sample 1: 60 grams of ice → Temperature decreased from 20.2°C to 16.0°C
• Sample 2: 59.9 grams of ice → Temperature decreased from 48.1°C to 44.2°C
• Sample 3: 71.1 grams of ice → Temperature decreased from 6.1°C to 1.0°C
• Sample 4: 122.6 grams of ice → Temperature decreased from 14.6°C to 3.3°C

From the data, we can conclude that as the amount of ice added increases (as seen in sample 4’s 122.6 grams, which resulted in a significant temperature drop compared to the others), the change in temperature tends to increase as well.

Thus, the best conclusion based on the results is:

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