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.
François-Marie Raoult (/ r ɑː ˈ uː l /; 10 May 1830 – 1 April 1901) was a French chemist who conducted research into the behavior of solutions, especially their physical properties. Life and work
This concept of proximity is applicable to everyday life since it has some influence over the people one meets and befriends within one's life, as outlined in the aforementioned studies. The formation of friendships was further studied utilizing the population of 336 adolescents within a small and geographically isolated Swedish town. [ 4 ]
Psychologists refer to this as the “peak-end rule”: People tend to prioritize remembering the peaks (i.e., the most exciting bits) and endings of events and experiences, and not so much what ...
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 law of attraction is the New Thought spiritual belief that positive or negative thoughts bring positive or negative experiences into a person's life. [1] [2] The belief is based on the idea that people and their thoughts are made from "pure energy" and that like energy can attract like energy, thereby allowing people to improve their health, wealth, or personal relationships.

The vapor pressure affects the solute shown by Raoult's Law while the free energy change and chemical potential are shown by Gibbs free energy. Most solutes remain in the liquid phase and do not enter the gas phase, except at very high temperatures. In terms of vapor pressure, a liquid boils when its vapor pressure equals the surrounding pressure.
