molar mass of hydrazine: 32.045 g/mol
melting point = 1.4 degrees C
Boiling point = 114 degrees C
Enthalpy of fusion = 12.6 KJ/mol
Enthalpy of vaporization = 41.8 KJ/mol
Molar heat capacity of the liquid phase = 98.9 J/mol x K
Molar heat capacity of the gas phase = 49.6 J/mol x K
The heat required to transform hydrazine from solid to gas is calculated.
