A 102.5g sample of metal beads was heated in a water bath to 99.5°C. The metal was then added to the sample of water (25.7g) and the temperature of the water changed from an initial temperature of 20.0°C to a fi al temperature of 41.5°C. What was the temperature of the metal at equilibrium?
What was the temperature change of the metal?
Calculate the specific heat and the atomic mass of the model.
