Calculate the internal energy and enthalpy of 1 kg of air occupying 0.05 m3 at 20 bar. If the internal energy is increased by 120 kJ as the air is compressed to 50 bar, calculate the new volume occupied by 1 kg of the air.
A certain alcoholic beverage contains only ethanol (C2H6O) and water. When a sample of this beverage undergoes combustion, the ethanol burns but the water simply evaporates and is collected along with the water produced by combustion.
