Question

Explain the Structure of Hygrometer​

Answer 1

Answer:

Dew-point hygrometers typically consist of a polished metal mirror that is cooled at a constant pressure and constant vapour content until moisture just starts to condense on it. The temperature of the metal at which condensation begins is the dew point.

Answer 2

Answer:-

❤A hygrometer has two bulbs: one wet and one dry. Both bulbs are like thermometers, though one is covered with a wet or dry towel. After a period of time, the water on the bulb evaporates and at that time, the temperature is measured on each bulb. The difference between the temperatures is noted.
