Based on the findings presented, we can evaluate the results:
- The cup with a temperature of 95°C (2 seconds) had the fastest dissolution time.
- The cup with a temperature of 72°C (4 seconds) had a slower dissolution time than the first.
- The cup with a temperature of 65°C (5 seconds) took even longer to dissolve the sugar.
- The cup with a temperature of 45°C (7 seconds) took the longest to dissolve the sugar.
From these observations, it can be concluded that:
A. The higher the water temperature, the faster the solute will dissolve.
This matches the data where higher temperatures correlate to shorter dissolution times. Therefore, the correct conclusion is A.
