Question

Should a thermometer bulb have large heat capacity or small heat capacity?

Short/Brief Note
Advertisements

Solution

The thermometer bulb should have large heat capacity because if it has lower heat capacity, it may expand at high temperatures resulting in false readings. Large heat capacity of the thermometer bulb ensures the correct reading of temperature by restricting the bulb from expanding.
