![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?
