Question 1 Report
Which of the following types of thermometers can be used to measure a range of temperature from -50°C to 50°? i. Clinical ii. Mercury iii. Alcohol-in-glass
Answer Details
The thermometer that can be used to measure a range of temperature from -50°C to 50°C is the alcohol-in-glass thermometer. Therefore, the correct answer is (iii) only.
Clinical thermometers are used to measure body temperature and usually have a range of 35°C to 42°C. Mercury thermometers, on the other hand, have a range of -38°C to 356°C but are not suitable for measuring temperatures below -38°C. Alcohol-in-glass thermometers, with their low freezing point, are suitable for measuring a wider range of temperatures, including those below -38°C.
