You have a 1.23-mol sample of water at ?30.°C, and you heat it until you have gaseous water at 140.°C. Calculate q for the entire process. Use the following data.
specific heat capacity of ice = 2.03 J °C-1 g-1
specific heat capacity of water = 4.18 J °C-1 g-1
specific heat capacity of steam = 2.03 J °C-1 g-1
H2O(s) ? H2O(l) ?Hfusion = 6.01 kJ/mol (at 0°C)
H2O(l) ? H2O(g) ?Hvaporization = 40.7 kJ/mol (at 100.°C)
