You are camping in a tent, you have some very hot water (700C) in a water bladder, but you realize thatin fact you do not have enough drinking water. Your plan is to melt the block of ice you have seen infront of your tent using the boiling water you have and then treat the entire quantity. You estimate thatthe ice block has about 1 kg and is at a temperature of about -200C. How much water do you need tomelt the ice and rise its temperature to 50C

your question asks at which segment does freezing occur.
