What material keeps ice cold?

Answer 1

Consider a drink with ice in it. Room temperature is warmer than the drink, so just by being in the room (or even worse, in your warm hand) the drink is going to absorb a certain amount of heat energy which tends to increase its temperature. However, any temperature higher than the melting point of water (0o Celsius) is going to melt the ice. And since it takes energy to melt ice, that energy cannot raise the temperature until the ice is all melted.

Answer 2

Materials with good thermal insulation properties, such as polystyrene foam, polyurethane foam, or vacuum-insulated panels, are effective at keeping ice cold by reducing heat transfer from the surrounding environment. Additionally, using reflective materials or adding a phase change material can also help maintain lower temperatures for longer periods.

Answer 3

Any insulator will help keep something cold. This includes but is not limited to winter coats, lard, and wool.

Answer 4

Apart from ice packs inside the cooler it would be the insulation material like foam elite that keeps the inside insulated from the hot ambient air.

Answer 5

either for cold put it in the fridge and warm put in oven at exactly 597 deggrees Fahrenheit exactly no more no less and it will keep it warm

Answer 6

Same thing to keep things hot, a vacuum space.

Answer 7

Put them in an insulated container. For example a vacuum flask keeps hot drinks hot and cold drinks cold.

Answer 8

I would say that styraphome works pretty well, from the research I have done all these years.

Answer 9

refrigerator, cooler, freezer

Answer 10

The amount of molecules going through it.
