In order to determine the heat capacity of their latest phone, CrabappleTM engineers cool the phone in the freezer to -39.9ºC. They then drop it into a calorimeter with some water in it that is at a temperature of 59.2ºC. The calorimeter (including the water) has a total heat capacity of 773.59 J/ºC. After a few minutes the temperature of the calorimeter is stabilized to 30.2ºC. What is the heat capacity of the phone?
