A pure lead bar 10 cm long is maintained with one end at T = 300 K and the other at 310 K. The thermoelectric potential difference thus induced across the ends is 12.8 μV. Find the thermoelectric power for lead in this temperature range. (Note: Q varies nonlinearly with temperature, but over this narrow temperature range, you may use a linear approximation.)

Consider two immiscible liquids such as water and oil. If a spherical oil molecule of radius r is taken out of the oil phase and placed in the water phase, the unfavorable energy of this transfer is proportional to the area of the solute (oil) molecule newly exposed to the solvent (water) multiplied by the interfacial energy, i, of the oil-water interface. The interfacial energy of the bulk cyclohexane-water interface is i = 50 mJ m-2, and the radius of a cyclohexane molecule is 0.28 nm. Using Boltzmann distribution, estimate the solubility of cyclohexane in water at 25 C in units of mol L-1.The concentration of water in water phase is 55.5 mol L-1.
