Heating will usually make a substance dissolve faster. Stirring makes things dissolve faster. Grind the substance into smaller 'bits'. Smaller particles have more surface are exposed to the water (solvent) so that it can dissolve faster.
Not all the solids will dissolve in water. Different solids have different solubilities (some will dissolve more than others). The higher temperature, the more will dissolve
homogenous mixtures dissolve eg salt & water. hetrogenous mixtures do not dissolve eg chalk powder & water.
Yes, hydrogen and nitrogen can dissolve in water. Hydrogen is sparingly soluble in water, while nitrogen is relatively insoluble in water.
- Sand does not dissolve in water- Plastic does not dissolve in water- metals do not dissolve in water
decreasing the temperature of the water
Not all solids will dissolve in water at all. Those that do dissolve do so at different rates, and it's also temperature-dependent.

A huge variety of common items along with chemicals dissolve in water. Sugar and salt will both dissolve in water, although at different rates.

it will evaporate it
No, sugar does not dissolve in sand because they are two different substances with different properties. Sugar is soluble in water, while sand is not soluble in water.
yes
High surface area of the water The colder the water the more dissolved oxygen Running water will dissolve more oxygen
homogenous mixtures dissolve eg salt & water. hetrogenous mixtures do not dissolve eg chalk powder & water.
It dissolves at different temperature
No. a solution doesn't need water to dissolve. it can be dissolve in different type of liquids. for example a regeform. regeform only can dissolve in petrol. nailpolish only can dissolve in spirits or acid
Lowering the temperature or increasing the pressure will cause a greater amount of oxygen gas to dissolve in water. This is because gases are more soluble in liquids at lower temperatures and higher pressures.
