does ice melt faster in salt, sugar, tap water or in room temperature air ?Science fair Project !!! =(?

Question

i neeed sources and websites and help on this project please !!!!

Answer 1

Tap water, air, salt,sugar (fastest to slowest)

The salt would prevent ice from forming, not necessarily melt it...The sugar would do the same although not as effectively...The rate of water molecules flowing over other frozen water molecules will break the crystalline structure of the all the water molecules by heating it up. The air would do the same although not as fast.

Answer 2

You know, if this is a science fair project, you're going to have to demonstrate that you actually tested this somewhere along the line. So go do it.

One hint. Be sure to test the melting of ice in a very large container for the liquids, because up to a certain point, the size of the container (the volume of the water) is going to matter.

Answer 3

The rate of melting will depend on the rate of heat transfer to the Ice from the surroundings. The rate depends on other things beside the chemical compositions of it surrounding, and you will need to minimize their effects. This is a link to an article on factors that effects the melt rate of ice.

Answer 4

Salt, without a doubt. That's why you put salt on your driveway when it's icy. You can actually lower liquid water's freezing tempurature by adding salt to it.

Answer 5

salt

Answer 6

Do your own homework, lazy.
