9. A student measures the volume of acid three times and the reading come out to be 27.25 ml, 27.38 ml, and 27.42 ml
respectively. But the actual volume of acid is 27.34 ml. Hence the
measurements taken by the student are precise as well as
accurate.
TRUE
FALSE

The answer is False because you can't measure acid three times

b. examine and describe cells

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.
