Question

Define latent heat of vaporization. Specify this value for water.

Answer 1

• Latent heat of vaporization is the heat energy consumed by one kilogram of a liquid to get converted to its gaseous state at its boiling point.
• It is a physical property.
• Its value is different for different liquids.
• The heat of vaporization of water is $2260{\mathrm{kJKg}}^{-1}$ which is also equal to $40.8{\mathrm{kJmol}}^{-1}$.
