Although it will still be edible, icing sugar will start to dry and crack after a few months.
since its non-polar and "like dissolves like" it will take a long time, the amount of time, not sure.
If u wanted to make icing then icing sugar is better to be used. But if only sugar is available then you must melt it down in a saucepan.. Search it on google for how to do it as I'm not completely sure. I Just use icing sugar
Icing sugar is when you take sugar and and mix it with a liquid to get the mixture to become thin. The icing is considered to be a thick liquid.
depense on the size of the cube
It takes about 5 seconds.
depends on how much sugar u put in the water
that depends on the quantity of water and the size of the sugar cube .......if i am correct
Yes, dissolve sugar in water until you have a saturated solution (ie no more sugar will dissolve) and let stand sufficiently long for the sugar to crystallize out again as the water evaporates. (This will take days to weeks).
It can take several hours for sugar to fully dissolve in a soda without being stirred. The rate of dissolution depends on factors like temperature, sugar crystal size, and saturation level of the liquid.
It would depend on the amounts of water and sugar
The sugar cube in the hot water will dissolve faster because there are more and higher energy collisions between the water molecules and the sugar molecules which will cause the sugar to dissolve faster.
There are many ways to make icing. The quickest is to mix icing sugar with a tiny bit of water. This takes less than a minute and produces an icing that will firm up in the refrigerator. (Icing sugar is a mixture of finely powdered white sugar and corn starch). Anything else you add - corn syrup, butter, shortening, ground nuts, food coloring - will take more time. You can also make icings from regular sugars by cooking and thickening with corn starch and so on. This will obviously take more time but will allow you to experiment and develope your own special treat.
