Most people prefer rock salt to melt ice (sidewalks, driveways, etc) over table salt because it does not cake on the surface like table salt. As for effectiveness, they all combat ice the same. All edible salts are kosher unless something is added to them to render the salt non-kosher such as flavourings. There is no specific type of salt that is "kosher salt".
none
apple juice will melt quickest.
Epsom salt melts ice slowly because it has a lower freezing point compared to regular water, meaning it needs to be even colder to freeze. As a result, it takes longer for the ice to melt as the epsom salt absorbs heat from its surroundings to raise its temperature enough to melt the ice.
because it has the most stuff that makes it melt
Chemically the two are the same, "kosher salt" is not strictly speaking the correct terminology, and "which melts the fastest" is sort of the wrong question to be asking anyway. That said, I would expect table salt (which is usually in smaller particles) to melt ice faster than the relatively larger koshering salt.
It takes 46:30 for kosher salt to melt ice!,
The frozen liquid that will melt the quickest is the one with the lowest freezing point, such as ice. Other frozen liquids like alcohol or salt water will take longer to melt due to their lower freezing points.
yes
Then part of ice melt, and table become wet.
Yes, salt really does melt ice, but it can refreeze if the temperature is low enough. The idea is to create a salt-water mix that has a much lower freezing point. Generally, rock salt may be used, occasionally with other binders such as sand. An alternative to using granular salt is to spray on a solution of brine, sometimes mixed with other minerals or chemicals (usually not ordinary antifreeze because it is ecologically toxic).
It will melt because the hot air will melt it.
It could burn or melt your table, (depending on what material the table is made out of)
