Salt in a water solution will LOWER the Freezing Point of the resultant solution. Therefore the Saltwater will have to be cooled to a lower temperature. All other things being equal, that should take longer than the plain tap water.
If you mean pure water by regular water, then regular water will freeze faster than tap water. This is because impurities in the tap water can distrupt the crystal formation during freezing and slightly lower the freezing point.
Tap water freezes faster than purified water. The impurities in tap water help the water to freeze at a faster rate than purified and natural water.
Salt Water
regular water!:)
Pure water freeze faster.
yes salt water does boil faster
On the contrary, it takes longer for salt water to freeze - it freezes at a lower temperature than fresh water does.
I think it is fresh water freezes faster because the salt melts ice.
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.
Sugar water freezes faster than salt water. However, regular tap water will freeze faster than either salt, or sugar water.
Plain water evaporate faster.
the salt prevents the water from getting cold
Salt Water
It doesn't. Tap water freezes faster than salt water.
Fresh water freezes faster than salt water, yes.
When water has a substance dissolved in it, it freezes at a lower temperature. Salt water has salt dissolved in the water, so it freezes at a lower temperature than fresh water.
regular water!:)
Saturated salt water freezes at a lower temp than saturated sugar water, which freezes at a lower temp than plain water. So plain water will freeze first then sugar water then salt water. Thank you QUIRKIE @ answerbag.com
