There is an insulated container with a mixture of 1 kg of water and 200 g of ice. Through a valve, 30 g of steam at 100C are injected into the system. Is it possible to know the final temperature of the mixture? Describe the procedure to calculate it. Now describe how you would calculate the amount of energy you would need to remove from the mixture for all of it (1.23 kg) to freeze. Is there an amount of steam that, when injected, will cause some of the water and ice to evaporate? Explain yes or no, and what allows or limits this from happening.
