In an Experiment, 30

question 53

Multiple Choice

In an experiment, 30.0 g of metal was heated to 98.0C and then quickly transferred to 50.0 g of water in a calorimeter. The heat capacity of the calorimeter with the water was 211 J/C. The initial temperature of the calorimeter was 27.0C, and the final temperature after addition of the metal was 32.5C. What is the value of the specific heat capacity of the metal?

• A)0.140 J/(g   C)
• B)83.0 J/(g   C)
• C)0.540 J/(g   C)
• D)0.591 J/(g   C)
• E)29.5 J/(g   C)
