4. Define Moisture and Hygrometer.
Answers
Answer:
A hygrometer is an instrument used to measure the amount of water vapor in air, in soil, or in confined spaces. Humidity measurement instruments usually rely on measurements of some other quantities such as temperature, pressure, mass, a mechanical or electrical change in a substance as moisture is absorbed.
Answer:
A hygrometer is a meteorological instrument that is used to measure the humidity of the air. A common way these devices work is by using a material that attracts moisture. This material changes depending on how hydrated it is.
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. Then each of the temperatures are used on a chart to find the relative humidity of that temperature and area.
