14.3 Gas pressure and temperature

Question 4

A student investigates the relationship between the pressure and volume of a gas at a constant temperature. Their results are shown in Table 1.

Table 1

Pressure ( $p$ ) / $kPa\text{kPa}$	Volume ( $V$ ) / $cm3\text{cm}^3$	$\times V$ / $kPa⋅cm3\text{kPa}\cdot\text{cm}^3$
105	40.0	4200
120	34.8	4176
140	30.0	4200
160	26.5	4240
185	23.0	4255

Explain whether the values in the column headed ' $\times V$ ' fit the equation:

p_1 \times V_1 = p_2 \times V_2
