distilled water
Most likely salt water. The salt accelerates the rate of corrosion, plus it has the oxygen needed for the metal to rust. Tap water has the oxygen too but with the salt also, it would cause the metal to rust more rapidly.
Put both in the freezer and use a timer. It must be in a freezer, because if you have ever heard of super-cooled water, a lack of vibrations causes water to remain liquid below the normal freezing point (0 degrees Celsius), that is if it is not disturbed at all.
Assuming there are equal concentrations of salt and sugar in each sample, the sugar water will freeze faster. Salt dissociates into its ions when dissolved, giving two ions for ever salt molecule. Because freezing point depression depends only on concentration, and the concentration of ions is double that of the sugar, sugar will freeze faster.
sea water has salt in into, tap water is cleaned so no nasty stuff is in it. http://dollarpocketmoney.com/?refcode=45624 look here for more info
Adding any amount of salt to water you obtain salt water; it is important to know the desired concentration.
Tap Water because adding substances to the water (salt or sugar) reduce the rate at which water will form ice crystals, making it freeze at a lower temperature.
Tap water, salt water will kill them
Plain Tap water would freeze fastest.Adding salt or sugar to tap water will cause a depression/decrease in freezing point. Hence it will be harder to freeze the tap salt or sugar water.
salt water and tap water
No tap water doesnt have salt as it goes through several filtres before reaching your tap.
salt water is more dense than tap water
When tap water and salt water are mixed together, the salt dissolves in the water and becomes part of the solution. The resulting solution will have a higher salt content than the original tap water.
Typically, you would add about 1 tablespoon of salt per gallon of tap water to make salt water.
Tap water.
It doesn't. Tap water freezes faster than salt water.
