It depends on amount of salt and water
Because of the salt in the water. You see, salt heightens the boiling point of water yet lowers the freezing point of water. So, naturally, something that takes longer to freeze would take longer to warm up, hence the fact that it takes longer to melt. Salt is a pretty amazing chemical/food. Hope this helps!
Sand is not used to melt snow, it is just used to increase friction, so the snow is not as slippery. Salt is used to melt snow, not sand. And salt works quite rapidly (but the actual speed will depend upon the ambient temperature).
It depends on how you're trying to freeze them, of course: if you have a freezer that goes to 0 degrees F, like the one in the back room of a supermarket, it'll take as long to freeze the salt water as it would plain water. (Salt water has a lower freezing temperature than plain water but if you have a cold-enough freezer, it'll freeze.) If you pour it into liquid nitrogen, it'll freeze instantly. It also depends on the temperature of the salt water at first. Also, which type of salt, and how pure the water is. It also depends on the concentration of salt.
That depends on (a) the size of the ice-cube, (b) the temperature of the water, and (c) the surrounding temperature.
It depends on how hot the water is
rock salt dose not melt salt
40 min
it takes 2 minutes for it to melt
It takes less time to melt the ice cube with salt.
The salt will take just a little bit more longer than the ice to melt. after the ice has melted. if you look where the water of the ice it. You will see little bullie like things in. soon after the bubbles will dissolve.
that depends on the size of the ice cube, how much salt, and the ambient temperature.
It depends on amount of salt and water
The answer depends on the temperature of the water.
because cold water molecules move slower at colder temperature.
It takes 46:30 for kosher salt to melt ice!,
About an hour.
