The densest water in the ocean is known as the Antarctic Bottom Water. It is formed along the Antarctic ice shelves where water freezes on the ocean's surface. The Antarctic Bottom Water plays a big role in the global circulation of ocean waters around the world. This dense water is
carried along the ocean floor, delivering oxygen and nutrients to the deepest parts of oceans.
Salia is making a model of the Antarctic Bottom Water. She mixes different amounts of salt into water samples. The water is all the same

Graph Salia's data on the line graph.
Predict the density of a 50-ml sample of water with 5 grams of salt added by placing a point on the graph.
Predict the density

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.

the answer is 75.0%.
