Use cold water. Using hot water means you need to wait for it to cool. It also means that - because of the way solubility works - you might not add enough water. If you want the sugar to dissolve quicker, stir it.
If you mean common table salt, which is sodium chloride(NaCl), then it does dissolve in water. It can become saturated to the point that no more will dissolve, but up to that point it does dissolve in water. Many, if not most, salts are soluble in water, though some are not.
Yes, sugar can dissolve even without stirring, and even in cold water, it just takes longer. It will eventually dissolve.
yes of course, there are somekind of solvents that dissolved oil like tween 80, tween 20 or DMSO if we want to dissolved it with water.
The increase of solvent temperature can directly correspond to solubility. For example increasing water temperature can increase its holding of solvated potassium nitrate (KNO3).
it depends upon what you want to dissolve ie if you want to dissolve a polar compound then hydrochloric acid is good but if you want to dissolve some covalent compound like benzene then water is better than HCl
because the plants want soil to grow and water too

The water temperature varies with the type of fish, but normally it should be about 75 degrees. Most aquarium heaters do a good job of keeping the temperature at this point. If your fish get sick you may want to raise the temperature to about 82 degrees.
That depends for what purpose you want the water. For example: if you want to broil some tea, it's best if the water is near the boiling point. At sea level, that would be 100 degrees.
It depends on the strength of the solution you want. 3.33g of AgNO3 is 0.0196 moles. Ish. So from there, you need to work out how much water is needed to create your required strength. 1.42 moles of silver nitrate is the maximum you can dissolve in 100g of water.
That depends on the temperature of the incoming water, what final temperature you want, and how fast you want it accomplished.
To safely water ski, the temperature of the water plus the temperature of the air should always be over 100 degrees F. However, you probably would want to wear a wet suit if it was that cold.
