A 12-inch diameter ball of pure cobalt metal at 225 °C was placed in 10.0 gal. of water at 15.0 °C. What is the final temperature of the water? Assume no heat is lost to the surroundings. (specific heat for cobalt is 0.421 J/g °C, density of cobalt = 8.862 g/cm3, 1 gal. = 3.785 L, 1 in = 2.54 cm, V(sphere) = 4/3 πr3)
◦ 169 °C
◦ 120 °C
◦ 69.5 °C
◦ 22.5 °C
