# Question

You have a 1.00-mole sample of water at 230oC, and you heat it until you have gaseous water at 140.oC. Calculate q for the entire process. Use the following data:

Specific heat capacity of ice = 2.03 JoC-1g-1

Specific heat capacity of water = 4.18 JoC-1g-1

Specific heat capacity of steam = 2.02 JoC-1g-1

H2O(s) → H2O(l) ΔHfusion = 6.01 kJ/ mol (at 0oC)

H2O(l) → H2O(g) ΔHvaporization = 40.7 kJ/ mol (at 100oC)

Specific heat capacity of ice = 2.03 JoC-1g-1

Specific heat capacity of water = 4.18 JoC-1g-1

Specific heat capacity of steam = 2.02 JoC-1g-1

H2O(s) → H2O(l) ΔHfusion = 6.01 kJ/ mol (at 0oC)

H2O(l) → H2O(g) ΔHvaporization = 40.7 kJ/ mol (at 100oC)
