In a closed container, one gram of water (1 cm3) is boiled under constant pressure of 1 atm (1.013 × 105 Pa) until it changes into steam.

The heat of vaporization at this pressure is Lv = 2.256 × 106 J/kg = 2256 J/g.

Assume that water vapor behaves like an ideal gas. The temperature of the steam is 373 K, number of moles of water vapor n = 0.0546 (g mol), the ideal gas constant R = 82.057 (cm3·atm/g mol·K).

(a) How much volume (in cm3) of steam is produced?

(b) How much work is done by the water when it vaporizes?

(c) How much has the internal energy increased?

8.33 kg of steam at temperature of 150 ∘C has 2.23×107 J of heat removed from it. Determine the final temperature and phase of the result once the heat has been removed if the heat is removed at constant pressure during the gas phase. For this problem, use the specific heat (at constant pressure) for water as 1850 J/kg∘C , the latent heat of vaporization as 2.256×106 J/kg , the specific heat of liquid water as 4186 J/kg∘C , the...

Let's say you completely boil 3.96 kg of rubbing alcohol at constant air pressure 99.7 kPa. What will be the resulting volume of vapor, in m3, assuming it behaves like an ideal gas? (Possibly useful: density of rubbing alcohol: 0.786 kg/liter, molar mass of rubbing alcohol: 60.1 kg/kmol, gas constant R = 8.314 kJ K−1 kmol−1. Beware K vs °C, Pa vs kPa, g vs kg, mol vs kmol, etc.)
At 0,00℃, for H2O (l) the saturation pressure P = 4,581 dry
At 0,00℃, for H2O (l) the saturation pressure P = 4,581 dry (i.e., the water vapor equilibrium pressure) and the vaporization heat, ?vapHm = 45,067 kJ mol-1. The steam can be regarded as an ideal gas. a) Calculate water pressure at 100,00?C with the assumption that ?vapHm is a constant between 0,00 and 100,00℃. b) Between 0,00 and 100,00℃, ?Cp,m for water evaporation can be adapted to the expression ?Cp,m = (-51,22 + 0,03153T) J K-1 mol-1. Derive an expression between 0,00 and 100,00?C for ?vapHm as a function of T as well as calculate P at 100?C.
