Ice Melting Science Fair Project Name
Our AP chem teacher decided to be nice and make us do a science fair project instead of a 9 weeks test.
Mine was on what substance melts ice fastest- salt, sand, pepper, sugar.
I don't know any clever names to put as the title on the board. Any suggestions? Thanks x]

@Nehalem: Not quite sure how people are getting this. I didn't do anything advanced.. I just tested each substance with ice melting several times. Everywhere I've searched has gotten the same result o-o But if I'm wrong I guess I'll just have to deal with it because it's already put together.
@dimo I thought it would be understood. My fault!
[quote=SeeMeTwice]@dimo Which substances [at room temperature]. I don't have the ability to effectively heat sand to very high temperatures and that variable isn't really needed o-o[/quote]
Thats a different question to the one you posted. Hence my response

@Searching
The reason that salt "melts" ice is that it lowers it's melting point, which has already been pointed out, which is fine. However, unlike the other substances (including salt) you can effectively heat sand to very high temperatures, so when added to ice it will melt it will pretty much vaporize the ice, something none of the other 3 substances can do. If the question is which of the four substances has the potential to melt ice the quickest, the answer is sand.

I might go with this one lol
@dimo @searching The salt melted the ice fastest, then sugar, because they were dissolve-able. The molecules in the salt/sugar mixed(?) with the molecules in the film of water over the ice making them move faster. Water molecules move faster than ice, so it melted... Or at least that's what I got from it.
The pepper and sand slowed the melting. Not sure why. Think it lowered the surface area exposed to the warmer air or something, but I'm not sure so I didn't put it.
Ice cubes are cool!
[quote=Searching]Seems like an interesting project. I haven't done it but I think the ice should make it melt faster since it lowers the melting point of ice by about 10 degrees if i'm not mistaken.
OT: Melting Ice?
Ice Melts!

Technically speaking it should be sand, while it does not react with the ice itself, sand can be superheated to ridiculously high temperatures while the other substances can not.
