Alexis predicts that the size of a magnet affects its magnetic properties. She designs an experiment using magnets of different sizes and paperclips to test her prediction. She takes
three magnets of different sizes (one small, one medium, and one large) and holds them over
a container of paperclips to see how many are attracted. Her results are shown in the table
below.
What should Alexis do next after examining her experimental results?

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.

there is none because earth is stationary and flat.
