The boiling point of water is measured four times.The results are 110.01°C, 110.02°C, 109.99°C, and 110.01°C. Which of the following statements best describes this measuring process?
i. Accurate but not precise
ii. Precise but not accurate
iii. Neither accurate nor precise
iv. Both accurate and precise
ii. Precise but not accurate
The measurements are close together, and thus precise, but they are far from the true value of 100°C, and thus not accurate.
