How much heat h1 is transferred to the skin by 25.0 g of steam onto the skin? the latent heat of vaporization for steam is l=2.256×106j/kg. express the heat transferred, in joules, to three significant figures?

The heat transferred by the steam to the skin is given by

where
m is the mass of the steam
is the latent heat of vaporization.

In our problem, the mass of the steam is (converting into kg)

while the latent heat of vaporization of the steam is

Substituting into the previous formula, we find the heat transferred to the skin:
