To analyze the table, we can look at the relationship between the amount of ice added and the resulting temperature change for each sample:
- Sample 1: 60 grams of ice resulted in a decrease of 4.2°C (from 20.2°C to 16.0°C).
- Sample 2: 59.9 grams of ice resulted in a decrease of 3.9°C (from 48.1°C to 44.2°C).
- Sample 3: 71.1 grams of ice resulted in a decrease of 5.1°C (from 6.1°C to 1.0°C).
- Sample 4: 122.6 grams of ice resulted in a decrease of 11.3°C (from 14.6°C to 3.3°C).
From the observations:
- There is no consistent pattern for each specific amount of ice and the resulting temperature change.
- However, as the amount of ice added tends to increase in Sample 4, there is a more significant temperature drop.
Now, let's evaluate the options provided:
a) As the temperature decreases, the kinetic energy of the sample increases.
- This is incorrect; as temperature decreases, kinetic energy decreases.
b) As the temperature increases, the kinetic energy of the water molecules decreases.
- This is incorrect; higher temperatures correspond to higher kinetic energy.
c) As the amount of ice added increases, the change in temperature increases.
- This seems to be most aligned with the observations. More ice generally results in a greater change in temperature (especially noted in Sample 4).
d) As the amount of ice added decreases, the temperature decreases.
- This is not necessarily true based on the table; the temperature change does not correlate directly in a clear manner without considering the amount of ice.
Thus, the best conclusion based on the results is:
c) As the amount of ice added increases, the change in temperature increases.
