The latent heat of vaporization (Lv) is similar to the latent heat of fusion (Lf), except that it relates to boiling rather than melting. For water, Lv = 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...
