EXPERIMENT 25 PRELABORATORY ASSIGNMENT - CALORIMETRY 1. The process by which a metal is heated to an exact, yet measured temperature involves the following. …Procedure. -fill beaker about 3/4 full of tap water and boil. -fill test tube with metal about 1/4 full and find the mass of the metal. -transfer metal to tube and place in hot water bath making sure all metal is below water. -boil until metal has reached temp of water. -measure out 100 mL of water into cup and record mass.When a metal at a higher temperature is transferred to water at a lower temperature, heat is inevitably lost to the calorimeter (Figure 25). Will this unmeasured heat loss increase or decrease the calculated value of the specific heat of the metal?

9.68 kj/mol. 26.5 kJ/mol. 2 of 15. Term. A 5.85 g sample of a salt with a molar mass of 84.10 g/mol is added to a calorimeter containing 53.51 g of deionized water. The initial temperature of the water is 21.68°C; the final temperature of the solution is 18.97°C. Assume the specific heat of the solution is the same as pure water, 4.184 J/g°C. Experiment 25 Post Lab: Calorimetry. Term. 1 / 5. Part A.1. The 200-mm test tube also contained some water (besides the metal) that was subsequently added to the calorimeter (in Part A.4).
