Is a Diet Coke control or variable science wise?

When conducting a scientific experiment, it is important to control for all variables that may affect the outcome of the experiment. This means keeping all conditions constant, except for the one variable that you are testing. In a scientific context, a control variable is a factor that is kept constant throughout an experiment to provide a comparison for the experimental variable.

In the case of a Diet Coke experiment, the control variable would be the Diet Coke itself. All other variables, such as the temperature of the Coke, the amount of time it is shaken, etc., would need to be kept constant in order to isolate the effects of the experimental variable.

For example, if you were conducting an experiment to test the effects of different temperatures on the amount of carbonation in Diet Coke, the control variable would be the Diet Coke at room temperature. You would then test different temperatures of Diet Coke to see how they affected the amount of carbonation.

By controlling all of the other variables, you can be sure that any changes in the outcome of the experiment are due to the experimental variable.
