Q. An insulated Thermos contains 190 cm3 of hot coffee at 83.0°C. You put in an 18-g ice cube at its melting point to cool the coffee. By how various degrees (in Celsius) have your coffee cooled once the ice has melted and equilibrium is reached? Treat the coffee as though it were pure water and avoid energy exchanges with environment. The specific heat of water is 4186 J/kg•K. The latent heat of fusion is 333 kJ/kg. The density of water is 1.00 g/cm3.
