The apparatus shows the use of electrolysis to split water into hydrogen and oxygen in the following reaction: H2O(l)→2H2(g)+O2(g)\text{H}_2\text{O}(\text{l}) \rightarrow 2 \text{H}_2(\text{g}) + \text{O}_2(\text{g}) . How can you explain the observed difference in volumes of the two gases produced?
