Question

Adding salt to water increases the water’s boiling point.

If you performed an experiment to test this hypothesis, which action would introduce confounding variables into your experiment?

Answer 1

Step-by-step explanation:

Adding other substances to the water besides salt, such as sugar or baking soda, would introduce confounding variables into the experiment. Other factors that could introduce confounding variables include using different volumes of water, using different amounts of salt, and heating the water at different rates. To minimize confounding variables, it is important to keep all variables constant except for the one being tested, which in this case is the effect of salt on the boiling point of water.
