Given that the specific heat capacities of ice and steam are 2.06 J/gÂ°C and 2.03 J/gÂ°C, the molar heats of fusion and vaporization for water are 6.02 kJ/mol and 40.6 kJ/mol, respectively, and the specific heat capacity of water is 4.18 J/gÂ°C, calculate the total quantity of heat evolved when 13.2 g of steam at 192Â°C is condensed, cooled, and frozen to ice at -50.Â°C.

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)
