# Consider a 81.7 g sample of H2O(g) at -10C. What phase or phases are present when -105 kJ of energy is removed from this sample?

Consider a 81.7 g sample of H2O(g) at -10°C. What phase or phases are present when -105 kJ of energy is removed from this sample? Specific heat capacities: ice, 2.1 J g-1 °C-1; liquid, 4.2 J g-1 °C-1; steam, 2.0 J g-1 °C-1, ΔHvap = 40.7 kJ/mol, ΔHfus = 6.02 kJ/mol. (Select all that apply.)
