The control group of this experiment is a glass of water with no ice cubes.

In an experiment, the control group is the one used as a reference to determine the real effect of the independent variable or factor being manipulated. Here are some examples:

In an experiment to test the effect of a specific medicine to cure cancer, the control group is those that do not receive the medicine.
In an experiment to test the effect of alcohol on concentration, the control group is those that do not drink alcohol.

Based on this, in the experiment presented the control group will be the glass with no ice because this is the most objective reference to evaluate how water displaces once ice cubes are added.
