To analyze the results in the table and draw conclusions, let's summarize the information presented:
1. Sample 1: Initial 20.2°C → Final 16.0°C with 60g of ice
2. Sample 2: Initial 48.1°C → Final 44.2°C with 59.9g of ice
3. Sample 3: Initial 6.1°C → Final 1.0°C with 71.1g of ice
4. Sample 4: Initial 14.6°C → Final 3.3°C with 122.6g of ice
Now let’s evaluate each option:
A. **As the temperature increases, the kinetic energy of the water molecules decreases.**
- This statement is incorrect; generally, as temperature increases, the kinetic energy of molecules increases.
B. **As the amount of ice added decreases, the temperature decreases.**
- This conclusion does not hold, as the relationship between the amount of ice and the temperature change is not straightforward. For example, in samples 1 and 2, a similar amount of ice resulted in a smaller temperature change compared to samples 3 and 4, which had larger amounts of ice.
C. **As the temperature decreases, the kinetic energy of the sample increases.**
- This statement is incorrect; as the temperature decreases, the kinetic energy of the water molecules decreases.
D. **As the amount of ice added increases, the change in the temperature increases.**
- This conclusion generally holds true across the samples: as the amount of ice added increases from sample 1 to sample 4, the change in temperature also appears to increase (e.g., 20.2°C to 16.0°C for 60g of ice shows a 4.2°C change, and 14.6°C to 3.3°C for 122.6g of ice shows a larger change).
Based on the analyses of each option, the most appropriate conclusion is:
**D. As the amount of ice added increases, the change in the temperature increases.**
1. Sample 1: Initial 20.2°C → Final 16.0°C with 60g of ice
2. Sample 2: Initial 48.1°C → Final 44.2°C with 59.9g of ice
3. Sample 3: Initial 6.1°C → Final 1.0°C with 71.1g of ice
