- Derive the Sackur–Tetrode equation for a monatomic gas confined to a two-dimensional surface, and hence derive an expression for the standard molar entropy of condensation to form a mobile surface film.Surface chemistry can be investigated by quantitative measure of photoelectron energies from surface directly using high vacuum methodsto decrease and increase If an electron with energy x is pulled away from the nucleus, the attraction between the electron and the nucleus decreases and the BE decreases till electron will be free of the nucleus. In contrast, in some molecules, less kinetic energy could be detected compared to more binding energy caused from such as: phase lags of the cantilever oscillation, relative to the signal sent to the cantilever's piezo-oscillation driver. Atomic force microscopy provides unique opportunities for visualizing other surface-dependent molecular interactions used to assess variations in materials viscoelasticity that lead to different The interact between surface and tip in Please use the following terms for your answer: contact mode short probe-sample distance tapping mode protein adsorption reduce thromboses surface reaction adsorbed gases induced…The sky is blue because sunlight at visible wavelengths scatters off nitrogen and oxygen molecules in the Earth’s atmosphere. The scattering is called Rayleigh scattering. This problem computes the optical depth of the Earth’s atmosphere to Rayleigh scattering. Assume that the atmosphere is composed of 80% N2 and 20% O2 by number and that these atoms are well-mixed throughout the atmosphere. Take the cross section to Rayleigh scattering of a single N2 molecule to be σN, and the cross section to Rayleigh scattering of a single O2 molecule to be σO. The total pressure of the air at ground level is P0. Take the atmosphere to be in hydrostatic equilibrium at constant temperature T, and constant gravity. The mass of the Earth is M⊕ and the radius of the Earth is R⊕. (a) What is the mean molecular weight μ of the atmosphere?
