It gives you a freezer burn
Adding salt to ice decreases its melting point. Adding salt to the top of ice helps melt the ice faster.
Ice cream melts when you boil it.
Ice will be cool at 10 degrees Celsius
nothing, it's only effective when salt is sprinkled ON the ice.
I assume you are asking why salt melts ice. It's very difficult to tell from your question... What happens, is that ice always has a thin layer of liquid water on it. When salt disolves in water it produces heat, melting the ice, providing more liquid water to disolve the salt into.
About 80% of the salt is initially not incorporated, and that 80% just drains back into the ocean.
They stay right in the salt shaker where they are suppose to be.
It melts slowly.
Salt decreases the freezing point of water, causing the ice to melt. This happens because the salt lowers the temperature at which the ice can exist in a solid state, leading to the ice absorbing heat from its surroundings and melting.
Salt release slowly the heat of dissolution and the temperature is increased.
Usually it'll blister and then scar.
The freezing point of water decrease because the dissolution is a process which release heat.
