Question description:
How could we increase the sensitivity of a liquid-in-glass thermometer such as the mercury thermometer? What is the basic principle for each method ?

There are some options:
1.Increase the size of the bulb.
2. Use thinner glass wall outside the capillary tube.
3. Decrease the size of the bulb.
4. Use narrower capillary tube.
What options would you choose ? Could you give me some detailed explanations ? Thanks a lot!
