Question

You have a 1.00-mole sample of water at -30 ^oC and you heat it until you have gaseous water at 140 ^oC. What is the energy absorbed by water in the whole process? Use the following data.

 

Specific heat capacity of ice = 2.03 J ^oC^-1 g^-1

Specific heat capacity of water = 4.18 J ^oC^-1 g^-1

Specific heat capacity of steam = 2.02 J ^oC^-1 g^-1

Heat of fusion () = 6.02 kJ mol^-1 (at 0 ^oC)

Heat of vaporization () = 40.7 kJ mol^-1 (at 100 ^oC)
