Answer :
Final answer:
Thermometers must be calibrated to ensure accurate temperature readings by correlating their measurements with reliable standards. This process is essential in various contexts, particularly in healthcare, to prevent harmful mistakes. Proper calibration involves checking against known temperature points, such as ice and boiling water.
Explanation:
Why Calibration is Essential for Thermometers
For thermometers to read temperatures correctly, they must be calibrated. Calibration is the process of correlating the readings of an instrument with those of a standard to ensure accuracy. Without proper calibration, thermometers can produce inaccurate readings, which can significantly affect outcomes in various applications, from cooking to clinical diagnostics.
For example, if a thermometer is used in a medical setting and is not calibrated, a patient's temperature may be inaccurately recorded, leading to potentially harmful decisions regarding their treatment. To calibrate a thermometer, you can immerse it in an ice-water bath to achieve a 0°C reference or boiling water to reach 100°C, checking its performance against these standard points.
- Calibration ensures accuracy in temperature readings.
- It is crucial in critical situations like healthcare.
- The process involves comparison against reliable standards.
Thus, regular calibration is vital for the reliability of thermometers and other measurement instruments.
