Evaporation of water takes place as a result of?
A reduction in the average kinetic energy of the liquid remaining after the molecules enter the gaseous state
Do the fastest or slowest moving molecules break away from the surface of liquid water to form water vapor?
The fastest moving water molecules will break away from the surfrace of the water to form water vapor, they have the energy to overcome the attractive forces between molecules.
Why does ice still melt in water?
Fire is pure energy being released. And it takes energy to move molecules around. Where ice is concerned, the water molecule has been sapped of all energy which causes it to remain in place and stick to other water molecules.. When the energy from fire comes in contact with the water molecule, the molecule absorbs the energy which causes the molecules to break away from each other and move. When the molecules break away and move is what causes a solid like ice to become a liquid.
How is a container of hydrogen gas different from a container of water vapor?
In a bottle of hydrogen and oxygen the two elements are intermingled but remain chemically separate and distinct. You have H2 molecules and O2 molecules in the same general space. In a bottle of water the hydrogen and oxygen are combined into a single substance, forming molecules of H2O.
What will happen to the water molecules when water boils?
It's actually a lot simpler than that. When liquid water boils, some of the water molecules in a liquid state become so energetic that they go into a gaseous state. They remain water molecules, completely unchanged in their internal composition. They just change how they relate to other molecules. The only "gas" that's released during boiling is water vapor. As such, you can reheat the same water a thousand times and you won't get any change in the boiling process (other than loss of the liquid as the water vapor wisps away). The water molecules in a liquid state will become water molecules in a gaseous state, and the process will be the same on the first, second, and thousandth time.
How are the water molecules positioned in the hot cup?
The molecules in a cup of hot water are spaced farther away from eachother than the molecules in a cold cup of water.

Why does air travel faster in water?
As opposed to travelling in what? But if you mean sound then its because sound is - technically speaking - a vibration of the molecules. It is slower in air because the molecules are farther away from each other, and thus the molecules take much longer to interact. In water, the molecules are closer together, and therefore pass on the vibration quicker. This also relates to why water takes sound much farther as opposed to air. :)
Molecules tend to move into area where there are more molecules?
That takes energy. Normal diffusion means that the molecules move away from each other (in other words ... to where there are less molecules).

after atoms and molecules of gases and liquids are heated they move away from the heat . what takes their place?
ions
What are molecules that are water fearing and try to stay away from water or another polar molecules?
Hydrophilic

Why does salt dissolve faster in hot water rather than cold?
In hot water the water molecules are moving at a faster rate than they move in cold water. The faster moving molecules hit the salt molecules with greater force and knock them away from the other salt molecules faster. That way the salt molecules dissolve in the water quicker.

Are the molecules in water close to each other?
The molecules in water are closer to each other than those of water vapor, but farther away from each other than those of ice.
When water evaporates what happens to the molecules?
When the heat is added to water, the atoms in the water particle get enough energy, they end up being so poweful, they are able to pull away from other atoms and bounce around. It's sort of like heating water, the water is getting boiled and the water turns to steam. When energy/heat is taken away from the gas form, the steam turns back into a water form. To make it simple, The molecules get energy from heat.
