Cold Salt Water is the densest. When there is less heat in a liquid, the particles are closer together. The salt also saturates the water and makes it even denser.
That's why boats float better in Cold Salt Water than in Warm Fresh Water.
P.S. Next time, put commas between the options.

Salt water melts faster than fresh water because salt lowers the freezing point of water. This means that salt water needs to be even colder than fresh water to freeze, leading to a faster melting rate when exposed to warmer temperatures.
Salt water has a higher salinity level compared to fresh water, which makes it denser and allows objects to float more easily. Fresh water has a lower freezing point than salt water, allowing it to freeze at a higher temperature.
To be considered fresh water, water must contain less than 0.05% salt concentration. This low salinity level distinguishes fresh water from salt water found in oceans and seas, which have higher salt concentrations. Fresh water sources include lakes, rivers, and streams.
The process of removing fresh water from salt water is called desalination. It can be achieved through methods like distillation or reverse osmosis. These methods involve separating the salt from the water to produce fresh drinking water.

salt water is densest
A basic answer is that the densest ocean water is the saltiest - a ship floats higher in salt water (sea) than in fresh water (lake). Also cold water tends to sink towards the ocean floor, or may form a layer mid way.
Fresh water tends to have no salt content. Fresh water is not ionized. Salt water is ionized with sodium chloride (salt). The average salinity of the oceans is roughly 35 ppt (parts per thousand).
The salt water has a greater density and the floating is easier.
Both fresh and salt water, depending on the species
Salt water melts faster than fresh water because salt lowers the freezing point of water. This means that salt water needs to be even colder than fresh water to freeze, leading to a faster melting rate when exposed to warmer temperatures.
Fresh and salt water are very different for one key reason, fresh water doesn't contain salt and salt water obviously does. There are different flora and fauna in fresh and salt water for this reason.
on fresh salt water
Salt water is water that has salt in it and it is found in oceans. Fresh water does not have salt and is found in rivers and lakes.
When salt water is poured into a glass containing cold tap water, the two liquids will initially mix together. Because salt water is denser than fresh water, it will sink to the bottom. Eventually, the two liquids may form distinct layers, with the denser salt water at the bottom and the less dense fresh water at the top.

Salt water is basically just fresh water with salt mixed in.
