Question

A 15.0 g of sample of silver is heated to 100.0 0C and then placed in a constant-pressure calorimeter containing 25.0 g of water at 23.0 0C. The final temperature of the system was measured as 25.0 0C. What is the specific heat of silver?

Answer 1

The sum of the heats added is zero.

Heat gained by silver+heat gained by water=0

masssilver*Csilver*(25-100)C+masswater*cwater*(25-23)C=0
