O It takes 34.7 kJ to heat up a 1.42-kg piece of an unknown metal from 25.0°C to 88.5 C. Suppose this piece of metal at 88.5°C is dunked in 3.00 gallons of water at 10 C. What is the final temperature of the system? Recall that the specific heat of water is 4.18 J/(g C), the density of water is 1 g/mL, and 1 gallon is 3.785L.
