A 30.0-g block of iron at 200.0°C is dropped into a liter of water in an insulated flask at 25.0°C and 1 atm. The specific enthalpy of iron is given by the expression Ĥ(J/g) = 17.3 T(°C). Final Temperature Check units and significant figures. Calculate the final temperature of the flask contents, assuming that the process is adiabatic, negligible evaporation of water occurs, negligible heat is transferred to the flask wall, and the specific enthalpy of liquid water at 1 atm and a given temperature is that of the saturated liquid at the same temperature. (Note: For this isobaric batch process, the energy balance reduces to Q = AH.) T = i ! °C Hint Assistance Used
