11 Φεβ 2021 · Get the definition and value of the ideal gas constant (R), which is also called the universal gas constant or molar gas constant.
The gas constant is calculated from R R U/M, where R U 8.31447 kJ/kmol·K is the universal gas constant and Mis the molar mass. Source: Specific heat values are obtained primarily from the property routines prepared by The National Institute of Standards and Technology (NIST), Gaithersburg, MD. cen98128_App-A_p865-892.qxd 1/8/10 3:29 PM Page 866
13 Δεκ 2023 · PV = nRT. relates the pressure, volume, temperature and number of moles in a gas to each other. R is a constant called the gas constant. The ideal gas law is what is called an equation of state because it is a complete description of the gas's thermodynamic state.
The gas constant occurs in the ideal gas law: where P is the absolute pressure, V is the volume of gas, n is the amount of substance, m is the mass, and T is the thermodynamic temperature. Rspecific is the mass-specific gas constant. The gas constant is expressed in the same unit as molar heat.
