400
Why is it possible to be able to pour multiple tablespoons of salt into a full glass of water, before the glass overflows?
It is possible to pour multiple tablespoons of salt into a full glass of water, before the glass over flows because the salt particles are so small that they can fit in between the particles of the liquid water, which are spread out.
