The correct Answer is:
To determine the temperature range that mercury thermometers can measure, we need to consider the physical properties of mercury, specifically its melting and boiling points. ### Step-by-Step Solution: 1. **Identify the Melting Point of Mercury:** - The melting point of mercury is approximately -38 degrees Celsius. This means that below this temperature, mercury will solidify and will not be able to measure temperature accurately. 2. **Identify the Boiling Point of Mercury:** - The boiling point of mercury is approximately 356 degrees Celsius. Above this temperature, mercury will vaporize and again will not be able to measure temperature accurately. 3. **Determine the Usable Temperature Range:** - The usable temperature range of a mercury thermometer is from its melting point to its boiling point. Therefore, the range is from -38 degrees Celsius to 356 degrees Celsius. 4. **Conclusion:** - Mercury thermometers can measure temperatures from -38 degrees Celsius to 356 degrees Celsius. ### Final Answer: Mercury thermometers can be used to measure temperatures up to 356 degrees Celsius. ---
