Illustration av antagande - 86929518. The gas constant (also known as the molar gas constant, universal gas constant, or ideal gas constant) is denoted by the symbol R or R. It is equivalent to the Boltzmann constant, but expressed in units of energy per temperature increment per mole, i.e. the pressure–volume product, rather than energy per temperature increment per particle. Chemistry and physics equations commonly include "R", which is the symbol for the gas constant, molar gas constant, or universal gas constant.

Thus, gas constant R value can be given as – Gas constant R = 8.3144598(48) J⋅mol −1 ⋅K −1.

The ideal gas law in terms of R is where P is the absolute pressure of the gas, V is the volume The gas constant, also known as the universal molar gas constant, is a physical constant that appears in an equation defining the behavior of a gas under theoretically ideal conditions. The gas constant is, by convention, symbolized R. The ideal gas law is a simple model that allows us to predict the behavior of quantitatively with a universal constant R that we call the ideal gas constant. Nov 29, 2018 The ideal gas law describes the behavior of an ideal sample of gas, and how that behavior is related to the pressure (P), temperature (T), volume May 22, 2014 gas constant.
