large
There are more particles in the beaker with a large amount of water compared to a beaker with a small amount of water, assuming the water is the only substance present. This is because the volume of water in the larger beaker contains more individual water molecules than the volume of water in the smaller beaker.
This is called a concentrated solution, not especially a saturated solution.('saturated' means: maximal possibleconcentration, this is not always a large amount!)
Not necessarily. The concentration of a strong acid in water depends on the amount of acid dissolved in the water. A solution is concentrated if there is a relatively large amount of solute (acid) dissolved in the solvent (water), and dilute if there is a relatively small amount.
When adding water to acid, it is important to add the acid to the water slowly while stirring continuously. This helps to prevent the acid from splashing out and causing any potential hazards, such as releasing heat or producing fumes. It's safer to dilute the acid gradually to avoid any violent reactions.
When small amount of phosphoric acid is dissolved in large amount of water, then the acid is the solute and water is the solvent.
territory
H2O means water; you can have a large amount of it, or a small amount of it. It's entirely up to you.
There is a large reservoir on the edge of the city that provides water for it.
I do not think that there is any difference. Petroleum engineers normally inject water into an oil reservoir to maintain the reservoir pressure (and hence the ability of the reservoir to pump oil to the surface). In the process and if the water injection wells are properly located, the injected water normally sweeps (pushes out) out more oil effectively flooding the reservoir and increasing the amount of oil that is recovered from the reservoir. This incremental oil will otherwise be left behind in the reservoir. Hence, in an oil reservoir where the natural aquifer is large and strong enough to maintain the reservoir pressure, water injection is unlikely to significantly increase the oil recovery from the reservoir.

A small amount of water will reach it's boiling point sooner than a large amount of water. It will not boil faster.
A very small amount - a pinch in a large container - would be enough. why would you want to do that though?
reservoir
Ice caps/glaciers
A small amount of water, engine will idle poorly and lose power. A large amount of water, engine will cease to run.
A dam , reservoir or lake.
In a small amount (a few ounces), probably not. A larger amount may effect water pump seals.
