Question

The latent heat of vaporization (L_v) is similar to the latent heat of fusion (L_f), except that it relates to boiling rather than melting. For water, L_v = 2.26 x 10⁶ J/kg. .970 kg of steam at 100°C (the boiling point of water) is put in contact with a 13.5 kg piece of metal. The initial temperature of the piece of metal is 70.0°C. When the piece of metal reaches 100°C, .0420 kg of steam has condensed.

    a.         How much heat was transferred to the metal by the steam?

            b.         What is the specific heat capacity of this metal?

            c.         The specific heat capacity of steam (constant pressure) is 2.02 x 10³ J/kg·°C. If the steam had started out at 105°C, all other things being the same as above, how many

                        kilograms of steam would have condensed?
