What is density? *
1 point
How much space something takes up
How many particles are in a given space
How much something weighs
What color something is
If something is more dense, what does that mean? *
1 point
The particles are closer together
The particles are further apart
It weighs more
It weighs less
As the air molecules in the balloon and bottle warmed up what happened? *
1 point
They got closer together
They spread further apart
They didn't change at all
The same principles of molecule movement that occurred in the cups also occurred in the balloon and bottle. (Hint: Did the molecules move the same ways?) *
1 point
True
False
What happened to the bubble seal when the bottle was placed in warm/hot water? *
1 point
It popped
It shrank (got smaller)
It expanded (got bigger)

1.VOLUME– The amount of space an object takes up. Basic Unit (SI Unit) for Solids – Cubic Meter, m3. LENGTH/DISTANCE – The measurement between two points.

2.one particle per cubic meter.

3.it means it is heavier

4.In a liquid the particles are still close together but a little further apart than in a solid.

5.In gases the particles are much further apart than in solids or liquids.

Explanation:

thats all i can type lol

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.
