A work of his was criticized by C.H.D. Buys-Ballout, who said that if this man's theory were true, gases should diffuse much more quickly than observed.  
A work of his was criticized by C.H.D. Buys-Ballout, who said that if this man's theory were true, gases should diffuse much more quickly than observed.  In response, this man modified his theory by suggesting that gas particles undergo random walks.  His name is sometimes applied to a theorem he developed that says that the mean kinetic energy is minus half the mean potential energy, known as the virial theorem. His namesake inequality says that the integral of the heat exchange over temperature is less than or equal to zero for a cyclic process.  Along with a Frenchman, he lends his name to an equation giving the slope of the coexistance curve.  FTP, give this man's name that is paired with Clapeyron in a famous equation.
