Determine the equilibrium temperature reached when 50 g of ice at 0°C is introduced to 20 g of steam at 100°C in a thermally insulated container. Given specific heat values for water, ice, and steam, find the final temperature resulting from the thermal energy exchange. Given the specific heat for water (Cwater = 1 cal/g°C), ice (Cice = 80 cal/g°C), and steam (Csteam = 540 cal/g°C).
