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.
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.
It depends on which salt you are talking about. Table salt has a melting/freezing temperature of 801oC, for example.
The melting point oof salt is far higher then the melting point of acetone.
Because the melting temperature of the ice is 32Â°F and the melting temperature of the salt is 1,474Â°F.
It helps because the temperature of the salt can stop the ice cream from melting
The melting point of sodium bromide (a salt) is 755 . Calculate this temperature in and in kelvins.
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.
The melting point of sodium chloride is 801 0C; at this temperature truffles and other organic addtives are burned.
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.)
The melting point will drop.
It lowers the melting temperature of ice
it lowers ice's melting temperature
-- 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
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).
salt water!! because it lowers the temperature of melting...
The answer depends on what the room temperature is
Yes. (BTW, the crystals are dissolving, not melting...melting occurs at a very high temperature).
No, salt does not stop ice from melting. In fact if the temperature is not too low it will cause ice to melt.
Salt lowers the melting point of ice, making it melt faster and at a lower temperature.
Salt will lower the melting point, and raise the boiling point of water.
No, it lowers the melting point, meaning it will melt when it is colder.
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.
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.
The salt will cause the ice to melt faster. the sugar shouldn't have much of a difference.
