Question

Investigate why if you are caught in a heavy snow storm,you should rather not EAT ice for hydration,but rather melt it to approximately your body temperature

Answer 1

The main reason for melting the snow first is that snow is colder, meaning it can cause frostbite to skin and increase the chances of hypothermia. Moreover, snow is less dense than water, so you will have to eat a lot of snow to obtain a considerable amount of water, which will be difficult.
