One approach to treating a liquid is to assume that it behaves as a "gas" of independent molecules, provided that: (1) the interaction of each molecule with the others is represented by a constant potential, -º; (2) each of the ni liquid molecules moves freely in a total volume v1 = nivo, where vo is the (constant) volume per molecule in the liquid phase. (a) calculate the chemical potential for ni liquid molecules at temperature t (b) treat liquid vapor (n, molecules in volume vg) as an ideal gas, and obtain chemical potential at temperature t (c) obtain an expression for the vapor pressure at temperature t in which the gas is in equilibrium with the liquid as a function of t, vo and 0. analyze the limits of high and low temperatures and comment physically.

If an athlete runs once around a track, back to the starting line, her average velocity is zero. true or false?

Antireflective coatings on solar cells are often made by applying a thin film of silicon nitride (sinx), which has an index of refractive of 1.2, on the top of the silicon solar cell, which has a refractive index of about 3.5. however, the sun emits radiation of various wavelengths which the solar cell absorbs, and the antireflective coating can only absolutely minimize the reflection of one of these wavelengths. the coating thickness is chosen to reduce the reflection of green/yellow light (e = 2.2 ev), which is the most intense color in the solar spectrum (shown below). which of the following coatings would minimize reflection of green/yellow light? the answer is 820 nm how? what is the angular width of the central maximum of an electron traveling at 2 x 108 m/s going through a single slit of width 1 mm.
