water that shoots out of a refridgeraor
Other substances that can melt ice include sugar, sand, calcium chloride, and urea. These substances lower the freezing point of water, causing it to melt at temperatures below the usual freezing point of 0 degrees Celsius.
heat
well water but other than that sugar
yes salt
Sodium chloride, or table salt, has a high melting point of about 801 degrees Celsius (1474 degrees Fahrenheit). Most stovetops do not reach temperatures high enough to melt salt; even at high heat, it will remain solid. When salt is spilled on a hot stove, it may heat up and can potentially caramelize or react with other substances, but it won't melt under typical cooking conditions.
You can apply heat, which makes the particles move faster. You can add salt (or many other substances, but salt is cheap) to depress the freezing point. You can put the ice under pressure; this is what happens under an ice skate blade so you glide on a thin film of water.
Heat, that's the only other thing I know of
When you try to melt salt with a blow torch, the salt will initially absorb the heat and start to melt, becoming a liquid. However, if you continue to heat the molten salt with the blow torch, it will eventually evaporate and release fumes of sodium chloride.
It does. Salt, or sodium chloride, melts at 801C or 1474F.
The salt dissolving in the water creates heat which then melts the ice.
probably salt will do the best not including heat
== == Salt lowers the freezing point of water by 32 degrees. If salt is sprinkled onto ice, it causes the ice to melt by a heat transfer. Out of the substances listed, salt would melt ice most efficiently.
