Plain water because the salt in the other water lowers the freezing point. All molecules must line up in order to freeze, therefore if adding salt, the Na and CL must line up with the water molecules in order to freeze. With plain water, the molecules line up faster and thus freeze faster.
Zinc will corrode in vinegar faster than salt water
of course they can be cut into a square. if you peel the skin of and cut it into pieces you can cut it into a square, rectangle, and many other shapes.
Salt freezes slower (i.e. at a lower temperature) than fresh water. Generally the greater the level of dissolved substances, the harder it is for ice crystals to form, so the greater the level of cooling required. Completely saturated saltwater freezes at -6°F / -21.1° C. == ==
it depends on the circumstances. boat type, wind..... In a controlled environment where water temp,current, and wind are equal you will be faster in fresh water. this is because fresh water is less dense thus creating less resistance. on the other hand you float higher in saltwater which can also create less drag. However mathematically because of the resistance of saltwater you can calculate that you will be able to go faster in fresh water despite floating higher in saltwater. Its not much faster. I haven't calculated it but if I had to guess maybe 1-2% faster. A more dramatic example would be easier to understand. lets compare freshwater vs mud or somewhat diluted mud 50 50. its a lot easier to figure out which you will go faster in. My boat will practically sit on top of the mud. less drag right? This is what most people think saltwater does for them. How fast are you going to go in mud? Not hard to figure that out. there is too much resistance, you probably wont go anywhere. Apply this same logic to saltwater vs fresh and you can see that the more dense a solution is the more resistance it will have.
Water freezes faster in metal compared to plastic due to the higher thermal conductivity of metal. This means that heat is transferred more efficiently from the water to the metal, allowing it to cool down more rapidly. In contrast, plastic has lower thermal conductivity, leading to slower heat transfer and a longer freezing time for the water.

Saltwater freezes slower than sugar water because the salt in saltwater lowers the freezing point of the water, requiring it to be at a colder temperature to freeze. Sugar does not have the same effect on the freezing point of water.
No. H2O expands as it freezes. I am a little rusty on my chemistry, but I remember it having something to do with dual-polarity (?) of a water molecule.

Yes, saltwater makes mascara run faster. Just like when you cry, those tears are a type of saltwater.
Hot water will freeze faster than vinegar because the hot water atoms will slow quickly and the vinegar will take longer to freeze because it contains an oil like sustance which take lionger to freeze.

Cold water freezes faster then warm water.
