✔ 最佳答案
1. True."Sensitivity" is the change in length of the liquid column per degree change in temperature. The unit is mm/C.
A larger bulb contains more liquid. This would surely give a larger increase in volume, hence a larger increase in length of the liquid column, for a degree rise in temperature.
2. Water. See the web-page below"
