Question 25
a.

Temperature can be measured using different scales. Complete the details for the missing temperatures in the table below:

TemperatureBoiling point of liquid nitrogenMelting point of lead
in ∘C^\circ\text{C}∘C(i)327
in Kelvin77(ii)
[2]
b.

In a thermodynamics laboratory, an engineer measures the volume of a fixed mass of argon gas inside a flexible cylinder at constant pressure. The table below shows the results:

Temperature in ∘C^\circ\text{C}∘CVolume in dm3\text{dm}^3dm3
-501.115
01.365
501.850
1001.865
1502.115

Identify the coordinates of the anomalous point from the table.

c.

Use the non-anomalous data points to find the temperature (in ∘C^\circ\text{C}∘C) at which the volume of the gas would theoretically become zero.
