The Salt transfers heat to the snow and causes the snow to melt and stay at 0C / 32F .
Actually, when you dissolve a salt in water the freezing point of water is lowered (like anti-freeze in your car radiator). So putting salt on snow lowers its freezing point so it melts (unless its new freezing point is higher than the actual temperature, in which case it doesn't).
It's a similar effect to trying to boil water that has a salt dissolved in it. It boils at a higher than normal temperature.

What melts snow and ice effectively?
Salt is commonly used to melt snow and ice effectively.
What happens when salt is sprinkled on roads when it snows?
The salt reacts chemically with the water in the snow, lowering its melting point. Depending on outside temp, this may be enough to cause the snow/ice to melt.
How do snow blowers work?
Snow blowers use a motor to power an auger, which breaks up and lifts snow. The snow is then discharged through a chute. The user guides the snow blower over the snow-covered area to clear the snow efficiently.
What is the priinciple behind the sprinkling of salt on the road when there is snow fall?
The principle behind sprinkling salt on the road when there is snowfall is to lower the freezing point of water. This helps to prevent ice from forming or to melt existing ice, making the roads safer for driving by improving traction. Salt dissolves in the liquid from the snow or ice, creating a brine solution that has a lower freezing point than water.
What does a cubic meter of salt weigh?
Salk cake = 1442 Salt course = 801 Salt fine = 1201 The weight and density of other bulk items can be found at: http://www.simetric.co.uk/si_materials.htm
Is there an alternative to salt for use on snow that is ecologically safe?
heat
Why does the NYC sanitation department use salt during a snow storm to treat the streets?
Because salt will basically melt the snow down into water.
Can you use a cooking salt for snow melting?
It is possible but it is more expensive.
Does snow contain salt?
No, snow does not naturally contain salt. Salt is typically added to snow by humans for de-icing purposes on roads and sidewalks.
Why do you use rock salt?
To melt the ice and snow and to give your tires grip on the road.
How can sodium be used in everyday lives?
You can eat table salt or use rock salt on roads to melt snow and ice in the winter.
Does snow have salt in it?
No, pure snow does not contain salt. However, it can pick up salt or other substances from the environment as it falls or melts, especially in urban areas where salt is used to de-ice roads.
Would putting salt on snow be dangerous?
no the salt only makes the snow melt faster
What salt does in snow?
KaBlamo!
If you throw rock salt out on your porch will it melt the snow and ice?
Yes, rock salt can help melt snow and ice on your porch by lowering the freezing point of water, making it easier to shovel or remove. However, excessive use of rock salt can damage concrete and harm plants nearby, so it's important to use it sparingly and avoid overapplication.
What could you use to get your car out of the snow?
Shovel, Tow Truck, Chains, Salt, Sand, Catlitter and Plow.
Using the salt on snow?
If you sprinkle a large amount of salt over snow/ice it will cause it to melt and keeps it from refreezing. If the snow is extremely thick you may have to lay down several layers of salt.
