Suppose 0.0290 kg of steam (at 100.00°C) is added to 0.290 kg of water (initially at 19.7°C.). The water is inside an aluminum cup of mass 44.7 g. The cup is inside a perfectly insulated calorimetry container that prevents heat flow with the outside environment. Find the final temperature (in °C) of the water after equilibrium is reached.
