Can you make ice last longer in room temperature?

Question

I am doing a science project for school and i need
some information on this for my references or
whatever.
So does any one know any ways of making ice last
longer in room temperature by adding stuff to it or
something like that?

Answer 1

Make ice cubes from distilled water, this removes solutes from water, solutes in a solvent depresses the freezing point, causing the ice to melt faster.

This works upon the same principle as sprinkling salt on ice to make it melt.


P.S. If you add stuff into it, it will melt faster, according to the equation: delta Tf=Kf M, where delta Tf is the freezing point depression, Kf is the freezing point depression constant, M is the molarity of the solute, which means the more stuff you add into the water, the more depressed or lowered its freezing point, the lower the freezing point, the larger the difference between room temperature and freezing point, and thus the ice melts even faster if you add stuff into water.

Answer 2

There isn't anything useful to add, but you can put an iced drink into a double-walled or insulated cup and compare the melting rate with that of ice in a glass tumbler or paper cup. The proper way to do the experiment is to weigh out equal amounts of ice shavings into each container, and add an equal amount of water from a supply at a particular temperature.

Answer 3

Changing the pressure, volume, and mass can make ice last longer. I am not sure if you want to add anything to the ice to change the chemical composition?

Answer 4

COVER UP THE ICE WITH SAW DUST. LONG TIME AGO,PEOPLE USE THIS THINGS TO PREVENT THE ICE TO MELT.BUT THE ICE WILL MELT AFTER SOME TIMES

Answer 5

by adding stuff on to it.

Answer 6

by sprinkling salt on it

Answer 7

No

Answer 8

yes you can do it by putting salt (NaCl) to it.
