Solution

If a third glow stick was added to the investigation but kept at room temperature, we would expect it to serve as a control in the experiment. This means it would provide a baseline for comparison with the other glow sticks that are subjected to different conditions.

The glow stick at room temperature would likely glow at a moderate rate - not as fast as one in a hot environment (which would cause the chemical reaction to speed up), and not as slow as one in a cold environment (which would slow the reaction down).

This is because temperature affects the rate of the chemical reactions inside the glow stick that produce light. At room temperature, these reactions would occur at a 'normal' rate, providing a standard against which to measure the effects of different temperatures.

In conclusion, the third glow stick kept at room temperature would likely glow at a moderate, steady rate, providing a control for the experiment.
