2.

350 g of ice at -10.00oC are added to 2.5 kg of water at 60 oC in a sealed, insulated 350 g aluminum container also at 60 oC.

At the same time, 50.0 g of steam at 140oC is added to the water and ice. Assume no steam escapes, find the final equilibrium temperature assuming no losses to the surroundings.
