Salinity

Real World Example

Imagine trying to fit all your clothes into a suitcase that's too small for your trip. Just like how you might struggle to balance what fits into your suitcase, water in the ocean balances how much salt it can dissolve. The more clothes you pack, the less room there is for other items, just as the more salt that's dissolved, the higher the salinity of the water becomes. Both situations involve managing limited space—whether it's in your suitcase or the water molecules trying to accommodate salt particles.
