The fresh water.
Fresh water.
saltwater boils the fastest
- Salt water is heavier than fresh water. - Fresh water freezes at zero degrees Celsius (32F), but salt water freezes at lower temperatures, depending on the amount of salt in the water. - Salt water boils at a higher temperature than fresh water.
Saltwater freezes too, just at a couple degrees lower than fresh water.

I'm going to assume that by 'kind of water' you mean between fresh water and saltwater (average ocean water). Fresh water freezes at 32 degrees F (0 degrees C), and saltwater freezes at 28 degrees F (-2 degrees C). Therefore, based upon these numbers, if 2 equal sized samples of salt and fresh water were kept frozen in a container at 20 degrees F, and the temperature of each was suddenly increased to room temperature, the salt water would begin to melt sooner, and therefore, slightly faster.
Fresh water will freeze first. This is because when water freezes the hydrogen bonds form a rigid structure (Ice). Salt and sugar molecules interfere with this formation.
Cold water freezes faster then warm water.
Fresh water freezes much much quicker.
Rain water is fresh water and does not have salt. Saltwater is not fresh and does have salt.
Saltwater is a solution because you can get fresh water and some salt and mix it and then you get saltwater.
