Does salt affect the temperature of water -boiling point - freezing point?
i would opt for the Freezing point. salt decreases the freezing point of water. so if water would normally freeze at 0C, saltwater would freeze at -3C.
Why does the freezing point affect the freezing of salt water?
It does not, but salt affects the freezing point. All solids are frozen. Each has a different freezing point. Ice is just the freezing point of water. But your computer keys are frozen too. Different substances freeze differently. But for your purposes, compare water to salt water. The salt in the water causes there to be more things in the water that disrupt the tight hydrogen bonds.Since freezing is tighter H-bonds, salt lowers the freezing temperature because it is harder to freeze it now since there is salt in it.
What is the effect of impurities on the melting point of ice and the boiling point of water?
The freezing point of water decreases when the number of dissolved molecules (or better particles) in the solvent increases. This is called freezing point depression and you can easily find the relation between the quantity of particles dissolved and the freezing point on Wikipedia.
Why does a test tube of fresh water freeze quickly in iced salt water?
The salt in the water lowers its freezing point, causing the water to become colder than 0 degrees Celsius. This rapid transfer of heat from the fresh water to the iced salt water speeds up the freezing process of the fresh water in the test tube.
What does ethylene do to the solution in a vehicles radiator?
Ethylene glycol mixed up to 50% with water, lowers the freezing point of the mixture, while remaining an excellent heat transfer medium. It protects the engine from either freezing or from overheating.
Why does water freeze before juice?
Because juice is mostly a solution of water, sugar, & other compounds. These other compounds added to water lowers the freezing point so it will freeze at a lower temperature than pure water. Look up freezing point depression for more information.
Is the melting point of impure water lower or higher than freezing point?
The melting point of impure water is lower than the freezing point. Impurities disrupt the crystalline structure of water, making it harder for the water molecules to align and freeze. This results in the impure water needing to be cooled to a lower temperature before it freezes.
What is the temperature at mars surface?
The surface temperature is VERY cold. It rarely gets up to the freezing point of water.
What is the freezing point of wood?
Well, honey, wood doesn't have a freezing point because it's not a liquid. It's made up of fibers and cells, not molecules like water. So, technically speaking, wood doesn't freeze – it can just dry out or burn.
Why does fresh water melt faster than salt water?
Because of the salt in the water. You see, salt heightens the boiling point of water yet lowers the freezing point of water. So, naturally, something that takes longer to freeze would take longer to warm up, hence the fact that it takes longer to melt. Salt is a pretty amazing chemical/food. Hope this helps!
What does ethylene glycol do to the solution in a vehicles radiator?
Ethylene glycol mixed up to 50% with water, lowers the freezing point of the mixture, while remaining an excellent heat transfer medium. It protects the engine from either freezing or from overheating.
In what two ways is adding antifreeze to the water in a car radiator useful?
The antifreeze provides corrosion protection until the corrosion package is " used up " and it raises the boiling point and lowers the freezing point of the water
