Consider a 1 kg block of ice at standard pressure. If it is initially at −5°C and is heated until it is steam at 109°C, how much total heat was added to the sample of water? Use the following thermodynamic values for your calculation:
cice = 2.09 J/g K
cwater = 4.184 J/g K
csteam = 2.03 J/g K
∆Hvap = 2260 J/g
∆Hfus = 334 J/g
1. 3950 kJ
2. 2710 kJ
3. 2620 kJ
4. 3040 kJ
5. 28.7 kJ
