Question 35
a.

Define thermometric property and state two examples of physical properties that can be used for the measurement of temperature.

[3]
b.

A newly manufactured liquid-in-glass thermometer has a blank stem with no graduations.

Describe the experimental procedures used to determine:

  1. the position of the lower fixed point on the Celsius scale.
  2. the position of the upper fixed point on the Celsius scale. Include any necessary precautions to ensure the accuracy of these points.
[4]
c.

Explain why:

  1. the graduation lines marked between the two fixed points are equally spaced.
  2. the thermal expansion of the glass bulb containing the liquid is typically ignored in simple calculations.
