Question 92

A manufacturer is designing a high-precision liquid-in-glass thermometer for laboratory use.

a.

Explain what is meant by the sensitivity of a liquid-in-glass thermometer.

[1]
b.

State two modifications to the physical design of the thermometer that would increase its sensitivity.

[2]
c.

Explain what is meant by the range of a thermometer.

[1]
d.

Explain why a design that produces high sensitivity typically results in a thermometer with a smaller range.

[2]
e.

Explain what is meant by the speed of response (or responsiveness) of a thermometer.

[1]
f.

State one design feature of the thermometer bulb that increases its speed of response, and explain why it works.
