A student immersed 200 pennies (each having a mass of 3 g) in boiling water. After they reached thermal equilibrium, she quickly fished them out and dropped them into 0.24 kg of water at 20°C in an insulated container of negligible mass. What was the final temperature of the coins? Pennies are made of a metal alloy—mostly zinc—with a specific heat capacity of 390 J/(kg • K). For water, c = 4.19 × 103 J/(kg • K).
