How does grounding cause dissipation of charge

Main Question or Discussion Point

When an object with a net charge is connected to the ground by some conducting material the net charge disappears. The only answer I was able to find was that the net charge gets spread out, which will clearly cause it to become negligible. What causes this to happen?

The "ground" can be considered as a reservoir of charges. If a material has too many electrons, the reservoir will take as many as it takes until the object becomes neutral. If it has a lack of electrons, the reservoir will give as many as it needs until it becomes neutral.

That is all you need to care about regarding this "ground". This won't be the first time you encounter a "reservoir" like this. You'll see one when you do thermodynamics and the Carnot cycle.
