The specific latent heat of vaporization of steam is _______.

Open in App

Solution

Specific latent heat of vaporization is the amount of heat energy required to change the unit mass of water at 100 °C into steam at 100 °C.
Its value is 226 x 10⁴ J kg^-1.
Hence, the specific latent heat of vaporization of steam is 226 x 10⁴ J kg^-1.
