Question

3. A chemist mixes 500 g of lead at 500°C with 1,200 g of water at 20°C. She then mixes 500 g of copper at 500°C with 1,200 g of water at 20°C. The specific heat
capacity of lead is 0.1276 J/g°C and the specific heat capacity of copper is 0.3845 J/g°C. What will be true about the final temperatures of the two systems?
A. The final temperature of the lead-water system will be equal to the final temperature of the copper-water system.
B. The final temperature of the lead-water system will be higher than the final temperature of the copper-water system.
OC. The final temperature of the lead-water system will be lower than the final temperature of the copper-water system.
D. Cannot be determined from the given information.
