Steam burn is more severe than that of boiling water because
Answer Details
The specific latent heat of vaporization of steam is 2.1 x 106JKg-1 while the energy required to raise the temperature of a unit mass of water from 0°c to 100°c = C x Dt = 4200 x 100 = 420000 = 4.2 x 105 JKg-1 ? steam possesses greater heat energy per unit mass
