A 31 g block of ice is cooled to -76°C. It
is added to 592 g of water in an 75 g copper
calorimeter at a temperature of 21°C.
Find the final temperature. The specific
heat of copper is 387 J/kg • °C and of ice is
2090 J/kg . °C. The latent heat of fusion of
water is 3.33 x 10 J/kg and its specific heat
is 4186 J/kg °C.
Answer in units of °C.
