| R | 8.3145 | J/K·mol |
| R | 1.9872 | cal/K·mol |

What is the value for R?
The value of R at atm that is at standard atmospheric pressure is R = 8.3144598 J. mol-1. K-1.
What is the value of R at STP?
The Gas Constant (R) If you use the first value of R, which is 0.082057 L atm mol-1K-1, your unit for pressure must be atm, for volume must be liter, for temperature must be Kelvin.
Why the gas constant R is called universal gas constant?
The gas constant is also known as the molar, universal, or ideal gas constant, denoted by the symbol R or R and 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.
Does R depend on nature of gas?
The value of the universal gas constant R depends on the units used for pressure, volume and temperature. Therefore, it depends on the units of measurement.
Is universal gas constant same for all gases?
From the gas equation, pV=nRT, R=pVnT. …
What is specific gas constant?
Specific Gas Constant The ratio of molar gas constant(R) to the molar mass(M) of the gas mixture is called The specific gas constant.
What is an ideal gas define specific gas constant?
(thermodynamics) The constant of proportionality appearing in the equation of state of an ideal gas, equal to the pressure of the gas times its molar volume divided by its temperature. Also known as gas-law constant; universal gas constant.
What is the specific gas constant of water?
Specific gas constant of water vapor R_w = \frac{1000R}{M_w} = 461.52J/(kgK), where R = 8.3144621J/(molK) is the molar gas constant and M_w = 18.01528g/mol is the molecular weight of water vapor.
Is it possible to liquefy an ideal gas?
An ideal gas cannot be liquefied because there is no intermolecular force of attraction between the ideal gas molecules. Due to large intermolecular spaces, there is no force of attraction between the ideal gas molecules and they are completely independent from each other.
What is the R for Torr?
| Values for the gas constant R | |
|---|---|
| Units | Value |
| J/mol K | 8.314 |
| m3 Pa/mol K | 8.314 |
| L torr/mol K | 62.36 |
Is P and N directly proportional?
Boyle’s law states that pressure (P) and volume (V) are inversely proportional. Gay-Lussac’s law states that pressure (P) and temperature (T) are directly proportional. Avagadro’s law states that the amount (n) of a substance is directly proportional to the volume (V).
