Answer :
Final answer:
Thermometers used to measure air temperature must be accurate to within 0.2 degree Fahrenheit. The correct option is: c) 0.2 degree Fahrenheit
Explanation:
Accurate measurement of air temperature is crucial for various scientific, industrial, and everyday applications. Thermometers employed for this purpose need to meet specific standards to ensure reliable data. The option 0.2 degrees Fahrenheit signifies a higher level of precision compared to the other choices.
A margin of 0.2 degrees Fahrenheit ensures that temperature readings are sufficiently precise for a range of purposes, including meteorological observations, climate research, and environmental monitoring. This level of accuracy is particularly important in scenarios where even small temperature variations can have significant consequences, such as in climate studies, weather forecasting, and controlled environments like laboratories.
