What will be kept the same (control) in the test?

The control variable is the one that is kept same in the test an throughout the test

Explanation:

The scientific constant that is kept constant throughout the experiment is not changed and the value remains constant throughout the experiment and they have strong influence in the results

To test the relationship between the dependent and the independent variables determination of the control variable is necessary and the resulting value changes if the control variables are not kept constant throughout the experiment

This will also bring about the co relationship between dependent variable and the independent variable

answer: h+ its less than oh

explanation:

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
