1. The problem statement, all variables and given/known data A copper container of mass 0.080kg and specific heat of 387Jkg-1K-1 contains 0.30kg of water and 0.040kg of ice at 0degrees. Steam at 100 degrees is passed into the water and its temperature stabilizes at 20.0degrees. Find the mass of the water left in the container. 2. Relevant equations Q = mc(T2 - T1) Q = mL 3. The attempt at a solution I don't know where to start. Can someone help me in how to approach this question?
