Help me solve question 2

1. Consider freezing a 2 cm × 2 cm × 2 cm cube of water. Calculate ΔH, ΔU, q, w, and ΔS for the process. At 0°C the density of water is 1.000 g/cm³ and the density of ice is 0.915 g/cm³. The enthalpy of fusion at that temperature is 334.0 kJ/kg. Atmospheric pressure = 1 bar. 2. Repeat the calculations in Problem 1 for evaporating a cube of water of the same size. The density of water at 100°C is 0.958 g/cm³. The heat of vaporization of water at the normal boiling temperature is 2257 kJ/kg. Assume that the vapor behaves ideally. Atmospheric pressure = 1 bar.
