C) Gather the materials that you will need to complete this project. Step 2: Draw a model of water in each state of matter.
a) You will use water as the subject of your poster. Start by drawing a representation of three
sealed containers.
b) In the first container, draw a representation of water molecules in a solid (ice). Be sure that
your model represents water at the molecular level. You may use a single circle to represent a
water molecule, rather than showing the individual atoms within the molecule.
c) Following the same method, draw a representation of water molecules in a liquid in the
second container.
d) Finally, draw a representation of water molecules in a gas (water vapor) in the third container.

"the periodic table is arranged in order of atomic number."

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.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
