Question

the calibration of this thermometer is 1 °c. recall that a single unit calibration allows us to estimate one additional digit in the measurement. what place value should the temperature be recorded to? 10°c 1°c 0.01°c 0.1°c

Explanation:

Step1: Understand Calibration Impact

The thermometer's calibration is \( 1^\circ\text{C} \), meaning each major division is \( 1^\circ\text{C} \). But between major divisions, we can estimate one additional digit.

Step2: Analyze Place Value

Since the calibration unit is \( 1^\circ\text{C} \), we can estimate to the tenths place (one decimal place). So the temperature should be recorded to \( 0.1^\circ\text{C} \), as we can estimate one digit beyond the calibration (which is in whole degrees, so adding a tenth place).

Answer:

D. \( 0.1^\circ\text{C} \) (assuming the options are labeled A to D with D being \( 0.1^\circ\text{C} \))
