Question

The thermometer bulb should have ___________

(a) High heat capacity

(b) No heat capacity

(c) Small heat capacity

(d) Varying heat capacity

I have been asked this question in a national level competition.

I need to ask this question from Thermal Expansion topic in portion Thermal Properties of Matter of Engineering Physics I

Answer 1

Right answer is (c) Small heat capacity

For explanation I would say: The thermometer bulb having small heat capacity will absorb less heat from the body whose temperature is to be measured. Hence the temperature of that body will practically remain unchanged.
