Question 18

Easy

A student investigates how the volume of a trapped sample of air changes as its pressure is varied at a constant temperature.

The student uses the apparatus shown in Figure 1.

A gas syringe with volume markings from 0 to 60 ml, with the plunger currently set at 50.0 ml. A thin tube connects the nozzle of the syringe to a digital pressure gauge showing a reading of 101.

The table below shows the results obtained by the student.

$P$	$V$	$\times V$
101	50.0	5050
126	40.0	5040
167	30.0	5010
253	20.0	5060

Suggest what the student should add to the column headings of this table.
