Question

Which instrument is used to measure atmospheric pressure?

• A. Thermometer
• B. Barometer
• C. Hygrometer
• D. Anemometer

Hint:

\textbf{Barometer = Pressure}.
\textbf{Thermometer = Temperature}, \textbf{Hygrometer = Humidity}, \textbf{Anemometer = Wind speed}.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Atmospheric pressure is the force per unit area exerted against a surface by the weight of the air above that surface.
Step 2: Detailed Explanation:
1. Thermometer: Measures temperature.
2. Barometer: Specifically designed to measure atmospheric pressure. Common types include mercury barometers and aneroid barometers.
3. Hygrometer: Measures the humidity or moisture content in the air.
4. Anemometer: Measures wind speed.
Step 3: Final Answer:
The Barometer is the instrument used to measure atmospheric pressure.
