What make ice melt slowly?

Answer 1

The best way to keep ice from melting is to keep its temperature below 0 °C (32 °F). This could be done by using other things such a dry ice (solid carbon dioxide) or liquid nitrogen to keep the ice below it's freezing temperature.

The easiest way to keep ice from melting is to insulated it. Any kind of insulation around the ice will prevent heat from the environment from warming the ice and melting the ice. This might include sawdust, a blanket, foam, rubber, vacuum insulation, wood, styrofoam, etc. The best insulation is a perfect vacuum.

Making ice with sawdust in it slows its melting down to an amazing degree. Near the end of WWII, the Brits and the Americans were researching making giant aircraft carriers out of huge blocks of sawdust ice (tough as concrete and it floats too!) cause they would almost be impervious to damage by bombs etc.

Answer 2

The cheapest and easiest method to lengthen the time of ice to melt is by spraying some sawdust over it. Saw dust insulates ice efficiently to help it melt slower. Also you can wrap in in aluminum foil.

Answer 3

because the salt is lowering the freezing point of the ice, therefore attracting warmer air to ice. indoors the plain ice may melt faster than ice with salt, however, outdoors salt will help to melt ice because it is attracting the warm air and melting the ice while plain ice is just attracting cold air.

Answer 4

When you sprinkle a salt on ice,temperature rises a bit for a very short time and then decreases a lot.This is due to the process of dissolution process occurring between the salt and ice(H2O).

Answer 5

well salt is a substance that can make ice melt faster, BUT the Quickest substance would be road salt which can be called CaCl2, table salt is NaCl. this is the difference

Answer 6

salt, pepper, sugar, and sand makes ice melt faster

but sand salt sugar and pepper melts ice faster than sand

Answer 7

Yes, snow often acts as an insulation.
