What happens when water’s salinity increases? mass decreases. freezing point decreases. buoyancy of objects decreases. the amount of dissolved minerals decreases.

The right answer is Freezing point decreases.

The explanation of the lowering of the freezing point of water is as follows: it is an entropic phenomenon, that is to say geometric. By interposing between the water molecules, the salt dilutes the water.

Let's see this in more detail: when the ice is in equilibrium in the water, there are in fact constantly ice molecules escaping into the water and, in equal numbers, molecules of water that come to settle on the ice. The salt ions dilute the water and cause the water molecules to be more distant (and therefore the water will not turn into ice).

The more water there is, the lower the salinity levels. The lower the water there is, the higher the salinity levels. The higher the salinity levels, the denser the water.

good luck

i still can't find this

i believe the answer would be b. hope it : )
