The heat of vaporization of a liquid is the energy
Chapter 6, Problem 96P(choose chapter or problem)
The heat of vaporization of a liquid \(\left(\Delta H_{v a p}\right)\) is the energy required to vaporize 1.00 g of the liquid at its boiling point. In one experiment, 60.0 g of liquid nitrogen (boiling point \(-196^{\circ} \mathrm{C}\)) are poured into a Styrofoam cup containing \(2.00 \times 10^{2} g\) of water at \(55.3^{\circ} \mathrm{C}\). Calculate the molar heat of vaporization of liquid nitrogen if the final temperature of the water is \(41.0^{\circ} \mathrm{C}\).

ANSWER:Step 1 of 3
Here, we calculate the molar heat vaporization liquid nitrogen
Heat of vaporization:
The amount of heat energy required to change liquid substances changes to gaseous state are called heat of vaporization.And also called as enthalpy of vaporization.
