Step 1:Let me solve this problem step by step:
Step 2:: Understand the Context
This is a calibration question related to thermometers. Calibration ensures accurate temperature measurement.
Step 3:: Analyze the Options
A. Drops to the floor - This is not a standard calibration trigger B. Submerges completely in water - This is a key calibration method C. Comes into contact with an allergen - Not related to calibration D. Falls in the soup - Not a calibration procedure
Step 4:: Recall Calibration Principles
Calibration of thermometers typically involves: - Using a known reference temperature - Ensuring accurate readings - Verifying instrument precision
Step 5:: Identify the Correct Answer
Submerging a thermometer completely in water allows calibration at the freezing point ($$0^{\circ}C$$ or $$32^{\circ}F$$).
The correct answer is B.
Step 6:: Explain the Reasoning
When a thermometer is fully submerged in pure water at standard atmospheric pressure, it can be adjusted to read $$0^{\circ}C$$ (freezing point), which is a standard calibration reference point.
Final Answer
Submerges completely in water
