An iron block of unknown mass at 185F is dropped into an insulated tank that contains 0.8 ft3 of water at 70F. At the same time, a paddle wheel driven by a 200-W motor is activated to stir the water. Thermal equilibrium is established after 10 min with a final temperature of 75F. Find the mass of the iron block.
