When water changes from the liquid phase to the gaseous (vapor) phase, energy is required for the H2O molecules to escape their mutual molecular attraction (the internal energy change ufg in the steam tables) and for the volume expansion (P·vfg). The total heat of vaporization for the phase change is represented by the enthalpy change hfg in the steam tables. Use the steam tables to calculate the fractions of energy for the volume expansion and for the molecules to escape...

J/mol Enthalpy of vaporization 2257 J/g 40660 J/mol Specific heat of solid H2O (ice) 2.087 J/(g·°C) * 37.60 J/(mol·°C) * Specific heat of liquid H2O (water) 4.184 J/(g·°C) * 75.37 J/(mol·°C) * Specific heat of gaseous H2O (steam) 2.000...
Question 4 1 pts When a gaseous oxygen atom gains an electron O(g) + → 0"(g), O AE O because energy is released in this process. O AE - Obecause the system reaches equilibrium. O AE > Obecause energy is released in this process. O AE <0 because energy is absorbed in this process. AE > Obecause energy is absorbed in this process.
