Answer:
Step-by-step explanation:
Ice in its original form is still water. Nothing has changed when it is melted except its physical form.
When something is burned, there is a chemical reaction and usually the reaction cannot be reversed. When you burn wood so that only ashes are left, you cannot wave a wand or do some other procedure to turn the ash back to wood.
If you want to change water back to ice, all you need do is store the water in a place that's below its melting point and before long you will have ice.
