प्रश्न
What does a large difference between the temperatures of a dry-bulb thermometer and a wet-bulb thermometer of a hygrometer indicate?

उत्तर
A large difference between the dry-bulb and wet-bulb temperatures indicates low relative humidity, because more evaporation from the wet bulb cools it down.
A small difference means high relative humidity, because less evaporation occurs due to more moisture already present in the air.
