You are interested in finding the pressure at which the first bubble of vapor will form from a liquid composition of ethanol (1) and benzene (2) (49 % by mole ethanol) at 313 K. The Margules parameters for this mixture are A12 = 2.173 and A21 = 1.539. Note that the vapor pressure of ethanol is 17.91 kPa and that for benzene is 24.38 kPa at 313 K. Find the pressure and vapor-phase composition.

Consider a 150-W incandescent lamp. The filament of the lamp is 5 cm long and has a diameter of 0.5 mm. The diameter of the glass bulb of the lamp is 8 cm. Determine the heat flux in W/m2 (a) on the surface of the filament and (b) on the surface of the glass bulb, and (c) calculate how much it will cost per year to keep that lamp on for eight hours a day every day if the unit cost of electricity is $0.08/kWh.
