The minimum practical application range for salt is a pavement temperature of 15-20 degrees F and above. While salt will melt snow and ice down to a pavement temperature of -6 degrees F, it can melt over five times as much ice at 30 degrees F as at 20 degrees F. Thus the effectiveness of salt is sensitive to small differences in pavement temperature.

Why does salt become ineffective at melting snow at certain temperatures?

Rock salt or regular sodium chloride loses its effectiveness for melting ice at about 5 degrees below zero F. This occurs because the freezing is more rapid than the melting ability. It is still melting but it cannot keep up with refreezing.


What temperature does salt freeze?

It depends on which salt you are talking about. Table salt has a melting/freezing temperature of 801oC, for example.


What conclusions can you draw about the melting points of acetone and table salt if table salt is a solid at room temperature and acetone is a liquid at room temperature?

The melting point oof salt is far higher then the melting point of acetone.


Why if you left an ice cube and salt at the sun the ice cube melts and the salt doesnt?

Because the melting temperature of the ice is 32°F and the melting temperature of the salt is 1,474°F.


Why Does salt help keep ice cube from melting?

It helps because the temperature of the salt can stop the ice cream from melting


The melting point of sodium bromide a salt is 755c Calculate this temperature in and in f kelvins?

The melting point of sodium bromide (a salt) is 755 . Calculate this temperature in and in kelvins.


What does the salt do to the melting point of water?

Salt lowers the melting point of water. The water will have to be at a colder temperature to freeze since the salt inhibits the waters ability to form ice crystals at the normal freezing temperature.


What is truffle salt melting temperature?

The melting point of sodium chloride is 801 0C; at this temperature truffles and other organic addtives are burned.


In science explain why more salt will disslove in the water when its temperature is greater?

Sodium Chloride (table salt) is an ionic compound that has a high melting point. The higher the temperature, the more you have reached its melting point, that means the higher the temperature the more the salt will be dissolved. (as long as the temperature is about 801 degrease Celsius, or 1474 degrease Fahrenheit, because that is table salts melting point.)


What happens to the temperature of the ice when salt is added?

The melting point will drop.


What effect does rock salt have on ice?

It lowers the melting temperature of ice


Why does salt melts ice faster?

it lowers ice's melting temperature


What are 5 liquids that do not have water?

-- pure alcohol at room temperature -- mercury at room temperature -- oxygen below its boiling temperature -- iron above its melting temperature -- nitrogen below its boiling temperature -- salt above its melting temperature -- gold above its melting temperature -- any other element or compound that is not H2O, above its melting temperature and below its boiling temperature


At room temperature table salt is a solid and mercury is a liquid what conclusion can you draw about the melting points of these substances?

We can conclude that the melting point of table salt is above room temperature (It's actually 801 deg C). The melting point of mercury must be below room temperature (- 39 deg C).


Which water will melt faster regular water or salt water?

salt water!! because it lowers the temperature of melting...


At what temperature does salt become a liquid?

The answer depends on what the room temperature is


Does the temperature of water affect how fast salt crystals or sugar crystals melt?

Yes. (BTW, the crystals are dissolving, not melting...melting occurs at a very high temperature).


Does salt stop ice from melting?

No, salt does not stop ice from melting. In fact if the temperature is not too low it will cause ice to melt.


Does salt make ice melt?

Salt lowers the melting point of ice, making it melt faster and at a lower temperature.


Goes salt lower boiling temperature of water?

Salt will lower the melting point, and raise the boiling point of water.


Does salt lower the temperature of ice?

No, it lowers the melting point, meaning it will melt when it is colder.


Does the amount of salt you add to water effect the temperature of the melting point of the ice?

yes


Why did temperature drop when you put salt into ice?

Because it made the ice melt as salt water has a lower freezing point than ordinary water. The melting process takes "latent heat of melting" out of the mixture and causes the temperature to drop.


What is in the salt that slows down the melting of ice?

Salt doesnt slow down the melting of ice. It actually speeds up the melting in most cases because the addition of salt lowers the temperature required for the water to freeze. That's why they will often put salt on the roads after a snow storm...to melt the ice.


How does the temperature affect ice melting with salt and sugar?

The salt will cause the ice to melt faster. the sugar shouldn't have much of a difference.
