internal energy
One mole of H2O(g)H2O(g) at 1.00 atm and 100 degrees Celsius occupies a volume of 30.6 L. When one mole of H2O(g)H2O(g) is condensed to one mole of H2O(l)H2O(l) at 1.00 atm and 100 degrees Celsius, 40.66 kJ of heat is released. If the density of H2O(l)H2O(l) at this temperature and pressure is 0.996 g/cm33, calculate ΔEΔE for the condensation of one mole of water at 1.00 atm and 100 degrees Celsius.

When 20.00 moles of H2(g) reacts with 10.00 mol of O2(g) to form 20.00 mol of H2O(l) at 25°C and a constant pressure of 1.00 atm. If 1366 kJ of heat are released during this reaction, and PΔV is equal to -74.00 kJ, then ΔH° = -1366 kJ and ΔE° = -1292 kJ.ΔH° = +1366 kJ and ΔE° = +1440 kJ.ΔH° = -1366 kJ and ΔE° = -1440 kJ.ΔH° = +1366 kJ and ΔE° = +1292 kJ.

The change in internal energy of a system (ΔE) can be described in terms of heat (q) and work (w) according to the equation ΔE = q + w. The conversion of 40 g of liquid H2O to steam at 1.0 atm leads to an increase in its volume. This expansion exerts 4.545 kJ of work on the surroundings. If the increase in internal energy of the H2O is 85.724 kJ, how much heat energy does this vaporization process use?...

Please show all work and explanations! Calculate ΔE, ΔS, ΔG, Q and W for the vaporization of 3.00 moles of liquid water to form water vapor at 100°C and 1.00 atm pressure. The standard molar enthalpy of vaporization of water is 40.67 kJ/mol. The density of liquid water at 100°C is 0.958 g/cm3 . Assume that the water vapor is an ideal gas, but be careful – the initial state is liquid water, so this is not simply an ideal...
