Raoult's law (/ ˈ r ɑː uː l z / law) is a relation of physical chemistry, with implications in thermodynamics.Proposed by French chemist François-Marie Raoult in 1887, [1] [2] it states that the partial pressure of each component of an ideal mixture of liquids is equal to the vapor pressure of the pure component (liquid or solid) multiplied by its mole fraction in the mixture.

A 2024 survey by AARP found that 20% of Americans ages 50 and over have no retirement savings and more than half (61%) are worried they will not have enough money to support them in retirement.
However, retirement can be full of hidden life lessons outside of finances — and they often don’t become an issue until you’ve actually left the workforce. Social isolation
Required minimum distributions (RMDs) are minimum amounts that U.S. tax law requires one to withdraw annually from traditional IRAs and employer-sponsored retirement plans and pay income tax on that withdrawal. In the Internal Revenue Code itself, the precise term is "minimum required distribution". [1]
The Margules activity model is a simple thermodynamic model for the excess Gibbs free energy of a liquid mixture introduced in 1895 by Max Margules. [1] [2] After Lewis had introduced the concept of the activity coefficient, the model could be used to derive an expression for the activity coefficients of a compound i in a liquid, a measure for the deviation from ideal solubility, also known as ...
The average retirement age in the U.S. -- ranging from 60 to 62 -- has held relatively steady since 2012, according to a study from Gallup and MassMutual. The average retirement age in 2023 was 62.
Köhler theory combines the Kelvin effect, which describes the change in vapor pressure due to a curved surface, with Raoult's Law, which relates the vapor pressure to the solute concentration. [ 1 ] [ 2 ] [ 3 ] It was initially published in 1936 by Hilding Köhler , Professor of Meteorology in the Uppsala University.
