---- ---- ---- Ice will melt faster on foil then on plastic. Foil is made of some kind of metal (usually aluminum). All metals are very good conductors of heat. (They are not insulators as another person wrote.) So, if you place ice on a sheet of foil it will act like a heat sink in reverse. That is, it will absorb heat from the surroundings and conduct it into the ice. Plastic, on the other hand, is generally not a good heat conductor. So it will tend to insulate the ice.
it is a greater conducter of heat than styrofoam
Ice will typically melt faster in a plastic or styrofoam cup compared to a paper cup. This is because plastic and styrofoam are better insulators, meaning they transfer heat more efficiently than paper. Therefore, the heat from the surroundings will more readily reach the ice in a plastic or styrofoam cup, causing it to melt faster.
Styrofoam is a better insulator of heat than plastic. The plastic allows the heat in and out and the cold in and out. The Styrofoam helps keep the heat in.
Putting the cup in the freezer keeps ice from melting. Those cups will slow down the melting rate, but if you've got ice at room temperature it's gonna melt eventually. Having said that, ice will melt slowest in a styrofoam cup.
Styrofoam insulates better than a single layer of plastic. If, however, you have one of those plastic cups that have an outer and an inner "wall" with a sealed air space in between, that should work better than the Styrofoam.
Ice cream will melt faster than yogurt, as yogurt does not melt.
air does not melt.
The ice will melt faster if placed outside rather than inside, regardless of how it's wrapped, due to higher ambient temperatures. However, wrapping the ice in plastic foil and aluminum foil will provide some insulation to slow the melting process compared to leaving it unwrapped.
Ah, I actually asked the same exact question about 3 years ago! I did a scientific experiment in my science class and to cut it short, glass. But your gonna have to do the rest of the work on your own. ;)
styrofoam, but warning fammable and unsafe for the environment!
Styrofoam is one of the most efficient insulators, and will insulate better than nearly any other common material... including wood.
The material of the container affects the rate at which heat is transferred to the ice. Materials with higher thermal conductivity, like metal, will melt the ice faster as they transfer heat more efficiently than materials with lower thermal conductivity, like plastic or Styrofoam. So, a metal container will lead to faster melting of ice compared to a plastic or foam container.
