Match each meteorological instrument on the left with its corresponding physical operational principle on the right.
- Six's thermometerDifferential expansion of liquids pushes steel indexes to mark extreme temperatures
- Wet-and-dry bulb psychrometerEvaporative cooling causes temperature depression indicative of moisture saturation
- Aneroid barometerExpansion and contraction of a flexible, evacuated metallic cell in response to weight of air
- Campbell-Stokes recorderFocal concentration of sunlight burns a trace line onto a calibrated card
Answer
Six's thermometer matches with liquid differential expansion driving steel indexes; Wet-and-dry bulb psychrometer matches with evaporative cooling temperature depression; Aneroid barometer matches with flexure of an evacuated metallic cell under air pressure; Campbell-Stokes recorder matches with solar ray focal concentration burning a calibrated card.
Each weather recording instrument operates on a distinct physical property: Six's thermometer uses differential fluid expansion to record maximum/minimum temperatures, the psychrometer uses evaporative cooling depression to compute relative humidity, the aneroid barometer relies on non-liquid capsule flexing under atmospheric weight, and the Campbell-Stokes recorder uses optics to focus direct sunlight and scorch duration marks on paper.
