A student investigated the electrolysis of dilute sodium sulfate solution. During the reaction, hydrogen gas was collected at the cathode and oxygen gas was collected at the anode. The volumes of both gases were recorded every 5 minutes.

Table 1

Time (minutes)	Volume of hydrogen ( $cm^3$ )	Volume of oxygen ( $cm^3$ )
0	0.0	0.0
5	8.0	4.0
10	16.0	8.0
15	24.0	12.0
20	32.0	16.0

Describe, using the data in Table 1, what the results show about the volumes of hydrogen and oxygen produced during this electrolysis experiment.
