Reading Thermometers: Reading Thermometers Worksheet Answer Key

Thermometers are essential tools for measuring temperature accurately. They have various applications in science, industry, and everyday life. Understanding how to read thermometers correctly is crucial to ensure accurate temperature readings.

Types of Thermometers, Reading thermometers worksheet answer key

• Liquid-in-glass thermometers:Use the expansion and contraction of a liquid, such as mercury or alcohol, to indicate temperature.
• Digital thermometers:Display temperature readings electronically, using sensors that convert temperature into electrical signals.
• Infrared thermometers:Measure temperature by detecting infrared radiation emitted by objects.

Tips for Reading Thermometers Correctly

1. Hold the thermometer vertically:This ensures the liquid column or digital display is aligned with the temperature scale.
2. Read at eye level:Look directly at the thermometer from the side to avoid parallax error.
3. Estimate between graduations:If the temperature falls between two graduations, estimate the value based on the distance between them.
4. Use the correct scale:Celsius (°C) is commonly used for scientific and medical purposes, while Fahrenheit (°F) is used in some countries.
