Q. An insulated Thermos contains 130 cm3 of hot coffee at 92°C. You put in an 18 g ice cube at its melting point to cool the coffee. By how numerous degrees (in Celsius) have your coffee cooled once the ice has melted and equilibrium is reached? Treat the coffee as although it was pure water and neglect energy exchanges with the 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 1.0 g/cm.
