In the specific heat capacity experiment, the unknown object has a mass of 0.073 kg and was cooled to -9 C. Then, it was placed in a calorimeter (mcalorimeter = 0.11 kg) that contain water (mwarter = 0.23 kg) at a temperature of 26 C. After 5 minutes the temperature dropped to 22.4 C. Determine the specific heat capacity of the unknown object. (cwater = 4186 J/kg. C and ccalorimeter = 900 J/kg. C)

Specific Heat (more precise) The heat capacity of an object indicates how much energy that object can absorb for a given increase in that object's temparature. In a system in which two objects of different temperatures come into contact with one another, the warmer object will cool and the cooler object will warm up until the system is at a single equilibrium temperature. Note the difference between the terms molar heat capacity, which has units of J/mol- Degree C, and...
