A 1.5 kg block of Ni at 100∘C is placed into 500 mL of water that has a temperature of 21∘C. What is the final temperature assuming the specific heat of Ni is 0.44 J/g−∘C and the specific heat of water is 4.184 J/g−∘C. Please answer with "degrees C" Hint: the total heat lost is equal to the total heat gained! 50 degrees C 30 degrees C 60 degrees C 40 degrees C
