🔍 Key Concepts

• Difference between measuring temperature, air speed/flow, and humidity • Common uses of anemometers, psychrometers, and aerometers • How air flow (or wind) is typically quantified in science and navigation

💭 Think About

• For each instrument, ask: what physical property does it primarily measure? • Which of these instruments would be used when you care about how fast air is moving through space, such as wind or duct flow? • Which of these instruments would be more appropriate in a weather or ventilation context versus a laboratory density or temperature context?

✅ Before You Answer

• Be clear on the definition of air flow rate (movement of air per unit time) versus temperature or humidity • Match each device to its main measurement: temperature, air movement, humidity, or density • Eliminate any instruments that do NOT directly measure how quickly air is moving
