It’s time to get started. Fill the plastic bottle to the brim with water. Then pour the water into a graduated cylinder or other measuring tool to measure the total capacity of the bottle. Note that you may need to fill the measuring tool multiple times. To recall how to use a graduated cylinder, watch this video on measuring volume before continuing. If you are using household measuring tools, use these conversions to record the exact capacity of the bottle in milliliters (mL). Visit the math review for help with converting units:

1 cup = 240 mL
1 tablespoon = 15 mL
1 teaspoon = 5 mL
What is the capacity of the bottle in milliliters?

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.
