A farrier makes horseshoes and is a specialist in equine hoof care. In making a horseshoe a farrier heats 0.950 kg of iron, hammers it into shape, and then drops it into a bucket containing 10.0 kg of water, which is at room temperature (20.00°C). A few minutes later the water and horseshoe have reached an equilibrium temperature of 22.25°C. The specific heat capacity of iron is 448 J/(kg-K); what was the initial temperature of the horseshoe before it was dropped in the water? Assume no loss of thermal energy to the surroundings.
A) 241.3°C
B) 243.8°C
C) 221.3°C
D) 198.8°C
