14.3 Gas pressure and temperature

Question 2

A researcher investigates the relationship between the temperature and pressure of a fixed volume of argon gas in a sealed rigid cylinder. Their results are shown in Table 1.

Table 1

Temperature ( $T$ ) / $K\text{K}$	Pressure ( $p$ ) / $kPa\text{kPa}$	$p / T$ / $kPa⋅K−1\text{kPa}\cdot\text{K}^{-1}$
280	126	0.450
300	134	0.447
320	145	0.453
340	152	0.447
360	163	0.453

Explain whether the values in the column headed ' $p / T$ ' fit the equation:

\frac{p_1}{T_1} = \frac{p_2}{T_2}
