Use data from the Integrative Example to determine how much heat is required to convert 25.00 mL of liquid hydrazine at 25.0 °C to hydrazine vapor at its normal boiling point.

Integrative Example

Use data from the table of physical properties of hydrazine, N₂H₄, to calculate the partial pressure of N₂H₄(g) when a container filled with an equilibrium mixture of N₂H₄(g) and N₂H₄(I) at 25.0 °C is cooled to the temperature of an ice–water bath.
