Final answer:
Thermometers must be calibrated to ensure they read temperatures accurately. Calibration involves aligning thermometer readings with known temperature standards. This process is vital for maintaining accurate measurements in various applications.
Explanation:
Correct Temperature Readings for Thermometers
For thermometers to read temperatures correctly, they must be calibrated. Calibration involves correlating the readings of a thermometer with those of a standard to check and ensure the instrument's accuracy. This process is crucial because even slight inaccuracies can lead to significant deviations in temperature readings, impacting experiments, weather stations, or even healthcare.
Calibration generally involves using known temperature points, such as an ice-water bath at 0°C and boiling water at 100°C. During calibration, the thermometer is adjusted according to these standards, enabling it to provide accurate readings when in use.
Unlike cleaning or sanitizing, which are essential for hygiene, calibration is specifically about checking and adjusting the accuracy of the readings a thermometer provides. Thus, to ensure proper functioning and reliable measurements, thermometers must undergo calibration.
