Answer:
The sensitivity of a thermometer is defined as the increase in the length of the mercury column per unit increase in temperature.
The sensitivity of a thermometer can be increased by-
1. Using a thermometer with a smaller bulb – A smaller bulb contains less mercury and therefore absorbs heat in a shorter moment in time.
2. A glass bulb with thinner wall – Heat can be transferred to the bulb straightforwardly.
3. Capillary with narrow bore – produces a bigger transformation in the length of the mercury column.
