water that shoots out of a refridgeraor
heat
well water but other than that sugar
yes salt
== == 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.
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
It does. Salt, or sodium chloride, melts at 801C or 1474F.
Organic salts may be used but these substances are more expensive.
The salt dissolving in the water creates heat which then melts the ice.
Conclusion: Cold substances will disolve less, and heated substances will disolve more. ------- The solubility of solid materials in water increase when the temperature is increasing; it is of course valable for sugar and salt.
probably salt will do the best not including heat
well you can just leave it out in your house or anywhere and it wont last it will just melt
