A 32 g block of ice is cooled to -75 (degreesCelsius). It is added to 511 g of water in a 71 g copper calorimeter at a temperature of 24 (degreesCelsius).
Find the final temperature. The specific heat of copper is 387 J/kg degrees C and the specific heat of ice is 2090 J/kg degrees C. The latent heat of fusion of water is 3.33x10^5 J/kg and its specific heat is 4186 J/kg degrees C.
