WebJan 13, 2024 · R is gas constant, but the units can be different like atm, torr, or bar. The ideal gas law is PV = nRT, where n is the number of moles, and R is universal gas constant. The value of R depends on the units involved, but is usually stated with S.I. units as: R = 8.314 J/mol. It is just a constant to use in the equation. WebThe specific heat (= specific heat capacity) at constant pressure and constant volume processes, and the ratio of specific heats and individual gas constants - R - for some commonly used "ideal gases", are in the table below (approximate values at 68oF ( 20oC) and 14.7 psia ( 1 atm )).
