The hotter it is the faster the molecules will move away from each other
Well, heating a cup of water would allow it to dissolve more of a particular substance if that is what you mean (given that the solute is able to dissolve in a polar solvent at all). For example, if you have two cups of equal volumes of water, one at 20 degrees celsius and the other at 35 degrees celsius, the water at the higher temperature (35 degrees celsius) would be able to dissolve more salt that the water at the lower temperature.
A Saturated Solution. In an unsaturated solution, more will dissolve, but once the solution is saturated, it is "full" and will not allow any material to dissolve in it at current temperature and other conditions.
In general, the amount of water will not have a very strong effect on how fast sugar dissolves. As long as the solution is not saturated (in other words, it is possible to dissolve more sugar), the rate of dissolving will not be affected. Since sugar is pretty soluble, only if the mixture is pretty much a syrup will the solution be saturated.
Gases are more soluble in liquids at higher pressure and low temperature.
Not a chemist but heating water makes things dissolve easier, pressure cookers allow water to reach higher temperatures without boiling. So a pressure cooker would probably be fastest. That or just boil some water.

Yes
Raises the temperature at which the water boilsAdding salt does not make the water boil faster, but makes the water boil at a higher temperature than 100 degrees Celsius. This may allow you to cook food in that water faster than in plain boiling water.

Yes. The much greater surface area of powdered soap will allow more water molecules to come into contact with the soap particles, dissolving it faster.
it lowers the temperature by forming hydrogen bonds that allow it to melt and boil faster
A device that will allow cooler condensate to pass and hold back the higher temperature steam
Low humidity + high temperature. The low humidity is necessary for rapid evaporation as the air can only hold a certin amount of moisture. The high temperature is necessary as liquids become more volitile at higher temps and therefor will evaporate faster
Perhaps. Temperature does not apply to quantum mechanical objects like particles. It applies to populations, such as a "mote" / body / air mass / planet / etc. There it means the individual atoms / molecules are moving with such-and-such an average speed. When dealing with a particle, it is better to refer to its kinetic energy.
Use hot water and more water. Remember though that there is going to be a certain amount of space in the water to dissolve a certain amount of salt. at this point no amount of heating will allow any more to be dissolved and is what is known as a saturated solution.
When substances is are put into solution the molecules of both the solvent and the solute are interspersed. Heating the solvent will cause it's molecules to move faster and thus allow the molecules of the solute to better access the spaces between them. Stirring and shaking also speeds up dissolving.
