In an experiment, 21.5 g of metal was heated to 98.0°c and then quickly transferred to 150.0 g of water in a calorimeter. the initial temperature of the water was 21.5°c, and the final temperature after the addition of the metal was 32.5°c. assume the calorimeter behaves ideally and does not absorb or release heat.
what is the value of the specific heat capacity (in j/g•°c) of the metal? j/g•°c
