Part of making comparisons involves contrasting unlike characteristics.

Part of making comparisons involves contrasting unlike characteristics is correct statement. It is understood that to make comparison we need different items which create comparison.

This is because if we compare similar items then we will not be able to judge the difference or compare which is better or which is not. Hence, every comparison involves contrasting unlike characteristics otherwise there will be no comparison between similar items.

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.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
