1) In doing the Calorimetry experiment, a student did not follow the directions exactly. How would the experiment be affected if no plot of temperature was carried out. Instead the student used the value of the water just after mixing with the metal as the maximum temperature.

2) A 102.5g sample of metal beads was heated in a water bath to 99.5deg.C.The metal was then added to a sample of water (25.7g) and the temperature of the water changed from an initial temperature to 20.0deg.C to a final temp. of 41.deg. C. (A.) What was the temperature of the metal at equilibrium? (B.) Calculate the specific heat and the atomic mass of the metal. What is the metal?
