Throughout the reflection, make sure you have a copy of the Student Guide and your data tables. Use the drop-down menus to complete the statements. The independent variable, the one that is intentionally manipulated, is ✔ the physical properties . The dependent variable, the one that you measure the response in, is ✔ the pH of the solution . The words with the check marks next to them are the answers your welcome .

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.
