背景知識
Background knowledge
1. 溫度計1. Thermometer（溫度計）
2. 濕度計2. Hygrometer（濕度計）
- Evaporation (Section 2.1)
- Design and make your own hygrometer
基本原理︰Basic principle:
一種常見的濕度計配有兩支水銀温度計，其中一支是濕球温度計，另一支則是乾球温度計。當濕球温度計上的水蒸發時，温度會下降，兩個温度計的讀數差可用來顯示大氣中的相對濕度。
另一種濕度計則利用有機物料（例如頭髮）的膨脹和收縮來顯示四周的濕度。
One common type of hygrometer is equipped with two mercury thermometers, where one has a wet bulb and the other has a dry bulb. When water on the wet bulb evaporates, the temperature will drop. The difference between the two temperature readings indicates the relative humidity in the atmosphere.
Another type of hygrometer makes use of an organic material (like hair) that expands and contracts in response to the surrounding humidity.

4. 雨量計4. Rain gauge（雨量計）
5. 氣壓計5. Barometer（氣壓計）
