Question

What is meant by saying that the latent heat of vaporisation of water is 22.5 Ã 105 J/kg ?

Answer 1

Answer:

The latent heat of vaporization of water is 22.5 × 105 joules per kilogram (or 22.5 × 105 j/kg). Hence it means that 22.5 × 10 5 J of heat is required to change 1 Kg of water (at its boiling point, 100°C) into steam at the same temperature of 100°C.
