Answer:
H1 = 63.3 kJ
Explanation:
When the steam at 100C contacts your skin, it is first condensed to water at 100C. The heat involved with this change in state is calculated using the latent heat of vaporization:
Q = ML = (25.0 g)(2.256 kJ/g) = 56.4 kJ
The water at 100C is then cooled to 34C. The heat involved with this temperature change is calculated using the specific heat capacity. (Because a temperature <em>change </em>is used here, it is not necessary to convert °C to K in order for the units to properly cancel)
Q = mcΔt = (25.0 g)(1kg/1000g)(4190Jkg⁻¹K⁻¹)(100C - 34C) = 6913.5 J = 6.9135 kJ
The total heat H1 that is transferred to the skin is the sum of the two heat values above:
H1 = (56.4 kJ) + (6.9135 kJ) = 63.3 kJ
