Question 142
a.

A student is validating the calibration of a standard laboratory thermometer.

Describe the steps you would take to check the accuracy of:

(i) the 0 ∘C0\text{ }^\circ\text{C}0 ∘C mark. *(ii) the 100 ∘C100\text{ }^\circ\text{C}100 ∘C mark at standard atmospheric pressure.

[2]
b.

A quantity of water is heated until its temperature reaches 115 ∘C115\text{ }^\circ\text{C}115 ∘C at standard atmospheric pressure.

In which state of matter is the water at this temperature?

[1]
c.

Temperature measurement depends on physical properties that change continuously with temperature (thermometric properties). Two examples are:

  • the volume of a liquid (as in a liquid-in-glass thermometer)
  • the pressure of a gas (at constant volume)

Name two other physical properties and the associated material or component that can be used to measure temperature.

  1. the ____________________\text{\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_}____________________ of ____________________\text{\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_}____________________

  2. the ____________________\text{\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_}____________________ of ____________________\text{\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_}____________________
