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 10^6 J/kg. .970 kg of steam at 100 degrees
celsius (the boiling point of water) is put in contact with a 13.5
kg piece of metal. The initial temperature of metal piece is 70.0
degree celsius. When the piece of metal reaches 100 degrees
celsius, .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 pressue) is
2.02 x 10^3 J/kg degrees celsius. If the steam had started out at
105 degrees celsius, all other things being the same as above, how
many kilograms of steam would have condensed?

An investigation has been completed similar to the one on latent
heat of fusion, where steam is bubbled through a container of
water. Steam condenses and the lost energy heats the water and
container. Use the following data to answer the question below:

You initially have 2.0kg of ice in 3.0kg of water at 0°C. How
much total heat must be added in order to convert 2.0kg of the
entire sample to steam at 100°C? Separately determine the amount of
heat for each stage of this process.
Specific heat capacities (J/kg∙K) Latent heats (J/kg)
c ice = 2090 Lf = 33.5∙10^4
c water = 4186 Lv = 22.6∙10^5
c steam = 2010
