For increased speed of response of an expansion pressure spring thermometer, the thermometer bulb should have a__________________?
Correct answer: D. All A , B & C
- A. Large area but small mass
- B. High thermal conductivity
- C. Small specific heat
- D. All A , B & C
Explanation
Fast thermometer response requires a large heat-transfer area, low bulb thermal mass, high thermal conductivity, and low specific heat. All three stated conditions therefore promote a faster response.
