The enthalpy of vaporization of liquid water at 100°c is 2257 kj/kg. determine the enthalpy for apordato of iuod eeat capacity of liquid water is 4 154 kjl(kg °c) and for water vapor is 1.859 kj/(kg °c)

Explanation:

The given data is as follows.

         ,      

        = 2257 kJ/kg,     = ?

For water, = 4.184

Formula to calculate heat of vaporization is as follows.

  =

Hence, putting the values into the above formula as follows.

=

=

            = 2257 kJ/kg - 376.56 kJ/kg

                                       = 1880.44 kJ/kg

Thus, we can conclude that enthalpy of liquid water at is 1880.44 kJ/kg.

the answer is the

catya your not at all which answer i've seen you do this on another question!
