Use the References to access important values if needed for this question. The following information is given for lead at 1 atm: boiling point = 1740 °C melting point = 328 °C AHvap(1740 °C) = 177.8 kJ/mol AHfus (328 °C) = 4.77 kJ/mol specific heat solid = 0.130 J/g°C specific heat liquid = 0.138 J/g°C What is AH in kJ for the process of freezing a 39.5 g sample of liquid lead at its normal melting point of 328 °C? kj
