Present Your Findings Write a conclusion of 250 words discussing this experiment and the results. Make sure to answer the following questions in your conclusion.

What did you do in this experiment? (List the procedural steps.)
Which parts of the separation process were the most time consuming? Why might this be important on an industrial scale?
Are there parts of the procedure that you would change if you could repeat this experiment? If so, what are they?
Give at least one example from industry where a mixture must be separated in order to obtain the materials that are useful to society.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
