WORD BANK: More Rise
Less Sink
Hot Top
Cold Closer

Explanation:
The particles in [type here] water are more spread out and become [type here] dense. This causes the water to and stay at the [type here]. In [type here] water, the particles move [type here] together and become [type here] dense. So, the cold water [type here] and stays at the bottom.

hot, less, rise, top, cold, closer, more, sink

Explanation:

I'm in high-school done this long time ago

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.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
