1.When a certain liquid-in-glass thermometer is heated, the glass expands more than the liquid. What would happen to the liquid column when temperature increases? Could such a thermometer be used to measure temperature?
2. 我本書話 increase一個liquid in glass thermometer 的bulb 的size,可以增加sensitivity, 但亦因為bulb 裏面的液體多了,heat up or cool down 裏面的liquid 要耐d, 所以give temperature 亦耐左,
我既問題就係, sensitivity 唔係指佢顯示所量度既溫度快唔快咩? 時間耐左又點算係增加sensitivty呢?
please help
