sugar is a covalent compound where as salt is an ionic compound,so salt while dissolving in the water splits.
This is mainly dependent of the 'total dissolved partical' concentration (mol/L):
So 180 g/L sugar: freeze at -1.86oC
and 175.5 g/L salt freeze at -(6*1.86) = -11.2oC
or 29.2 g/L salt will freeze at the same as 180 g suger: -1.86oC
Assuming you had equal amounts of each, the pure water would freeze first...Adding sugar or salt to water lowers its freezing point, meaning that more energy would be required to be removed from salt water and sugar water to freeze it
that last answer didn't make sense because he is a moron... test it ur self instead of guessing or on theory
Ok that was mean and i really need help with my Science project fix it or be reported. Thanx
If the same weight of sugar or salt is used, and the same amount of water in every case, AND the heat transfer situation is the same (meaning that the same temperature at start, same freezer temperature, and using the same container, same freezer, location, airflow, etc., etc.) the water will freeze faster than the sugar water, which will freeze faster than the salt water, assuming that the freezer is cold enough to freeze them.
The more "stuff" you dissolve in the water, the lower the freezing point of that solution, which means there will be both a delay in the start of freezing (again assuming the same starting temperature and heat transfer situation) of the solutions (water with stuff dissolved in it, as opposed to the pure water), as well as a slowing of the solution freezing because the temperature difference between the solution (now freezing at a lower freezing point) and the freezer is smaller (smaller temperature difference means less heat energy transferred in the same period of time).
Sugar is a heavier molecule than salt, meaning that if the weight of a pile of salt and a pile of sugar is the same, there are more salt molecules than sugar molecules. Salt also is ionic, so each molecule comes apart into two pieces in solution, so each molecule counts double for determining the amount of freezing point depression (the technical term).
plain water cause it has a higher temperature
Sugar water will freeze faster than salt water.
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.
Sugar sinks at the same rate in warm or cold water. Sugar dissolves faster in warm water.
Sugar dissolves in water faster than salt because of the structure and bonding of its atoms. The atoms of Sugar are bound very loosely whereas the atoms of salt are tightly bonded as compared to the sugar atoms. That is why sugar dissolves faster than salt.
yes
Sugar dissolves faster than salt. When a substance dissolves into another substance, it turns into a solution. The substance that is dissolved is the solute.
no salt water does not freeze faster than sugar.
Salt water will.
Sugar water freezes faster than salt water. However, regular tap water will freeze faster than either salt, or sugar water.
It doesn't
Water will freeze faster than salt water.
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.
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.
Assuming you had equal amounts of each, the pure water would freeze first...Adding sugar or salt to water lowers its freezing point, meaning that more energy would be required to be removed from salt water and sugar water to freeze it
For salt water to boil faster than plain water, the salt concentration would have to be fairly high. In addition, the salt water would need to be a salt water solution before putting the pot on to heat because of the density of the water content itself.
Pure water freeze faster.
Pure water freezes faster, although as anti-freeze goes, sugar is not one of the more potent. Try salt instead.
Sugar water will freeze faster. Salt lowers the temperature at which water freezes. That is why they put salt on the roads and on sidewalks in snowy areas. Sugar in water should have little to no affect on the rate of freezing.
