An ambient temperature that is greater than the ice will cause it to melt.
Heat is added to ice to make it melt.
Yes, the more salt the better to melt the ice.
no, it just makes more ice
yes
Salt lowers the melting point of ice, making it melt faster and at a lower temperature.
i would had thought the acid in oranges would make the ice melt faster.
to make an insulator prevent ice from not melting is to use tinfoil and dirt.
salt
maybe
Yes it does
put it in the fricken oven
keep it in liquid ammonia
