Why would a doctor most likely restrict a patient’s contact with other people while the patient receives internal radiation?
a. the patient’s stress and anxiety would be eliminated.
b. high levels of radiation can diffuse through the patient’s skin.
c. social contact would increase the effect of the radiation treatment.
d. radioactive material can leave the patient’s body through saliva, sweat, and urine.

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.
