[@Spectrojamz]

Around 23:00. The question having Aluminum,Iron and Water... There's a mistake behind his approach. The Element with the highest temp will lose heat to the others with low temp. Simply put... Aluminum at 120°c will lose heat to Iron metal at 90°c and water at 15°c cos the Conservation law of heat says that heat will flow from the higher region to the lower. Asides that.... Still the greatest KZbin tutor!!!

[@user-vb8km8br8p]

Best explanation, but there's an error in your calculation. Try and have a look at the question where it says " A 100g sample of aluminum ( c=0.90 J/g C) at 120C" instead of using the heat temperature of the sample of Iron, you used the 120C temperature of Aluminium.
