1. The problem statement, all variables and given/known data calculate the final temperature when 20 grams of steam at 100°C is added to 100 grams of ice at -40°C. 2. Relevant equations Q=mcΔt and Q=ML 3. The attempt at a solution I tried solving this problem using -ΔQheat = ΔQcold, but the final temperature that I found was past 100 °C which is impossible because the steam's temperature is only at 100°C. I believe I need to find how much of the ice actually turns into water and how much of the steam actually condenses into water but I don't know how to go about doing that. Thank you for the help.
