SUMMARY
To convert 20.0g of H2O(s) at -10°C to steam at 110°C, a total of 12,765.4 joules of heat must be added. This process involves five distinct steps: heating the ice from -10°C to 0°C, melting the ice to liquid water, heating the liquid water to 100°C, vaporizing the water to steam, and finally heating the steam to 110°C. The specific heats used are 2.09 J/g°C for ice, 4.184 J/g°C for liquid water, and 1.84 J/g°C for steam, along with the heat of fusion (334.7 J/g) and heat of vaporization (2259.4 J/g).
