Problem: A 0.4 kg block of iron, with a specific heat of 448 j/(kgK),is initially at 500 degrees Celsius. The iron block is then dropped into 20 kg of water with a specific heat of 4186J/(kgK) and a temperature of 22 degrees Celsius.
Part A: What is the final equilibrium temperature of the block and water?
Please show all steps to determine the final equilibrium temperature of the block and water.
