(a) Explanation Write the expression for theenergy transferred by heat, Q c o l d = − Q h o t (I) Here, Q c o l d is the energy transferred in cold medium and Q h o t is the energy transferred in hot medium. Rewrite the above equation for the aluminum, Q A l = − ( Q w a t e r + Q c a l o r i ) (II) Here, Q A l is the energy transferred in aluminum, Q w a t e r is the heat transferred in water and Q c a l o r i is the heat energy transferred in calorimeter. Substitute m A l c A l ( T f − T i ) for Q A l , m w c w ( T f − T i ) for Q w a t e r and m c c c ( T f − T i ) for Q c a l o r i in the above equation, m A l c A l ( T f − T i ) A l = − ( m w c w + m c c c ) ( T f − T i ) w (III) Here, m A l is the mass of the aluminum, m w is the mass of the water, m c is the mass of the calorimeter, c A l is the specific heat of the aluminum, c w is the specific heat of the water, c c is the specific heat of the calorimeter, T f is the final temperature and T i is the initial temperature (b) To determine Is the ratio of the result value within 15 % .
