(20pts). An unknown mass of
iron at 90°C is dropped into an
insulated tank that contains 80L
of water at 20°C . At the same
time, a paddle wheel driven by a
200 - W motor is activated to stir
the water. Thermal equilibrium is
established after 25 minutes
with a final temperature of
27°C. Determine the mass of
the iron. Neglect the energy
stored in the paddle wheel, and
take the density of water to be
