Question

In a physics experiment, Wendy immersed a copper of mass 300g in 100 degree C in boiling water and left it there for several minutes. She then transferred the cube to 0.2 kg of water at 10 degrees C. The final temperature of the mixture was 21 degrees C. What value did she get for the specific heat capacity of copper?

Answer 1

The sum of the heats gained is zero (one will be negative heat gained, or heat lost).

Masscopper*ccopper*(21-100)+masswater*cw*(21-10)=0

solve for ccopper
