From the Wikipedia: "In SI units... R has the value 8.314 J·K−1·mol−1." That's can also be expressed as J/(K x mol). In other words, energy divided by (temperature x amount of substance).

Does the gas constant R vary with temperature?
No, the gas constant, or any constant, is constant meaning it doesn't change.
What is the gas constant R for methane gas?
314
What is characteristic gas constant?
"Characteristic Gas Constant"The constant 'R' used in the characteristic gas equation PV=RT , has a constant value for a particular gas and is called 'Characteristic gas constant' or 'specific gas constant' . Its value depend upon the temperature scale used and the properties of the gas, under consideration.The value of R will be.For atmospheric pressure air,R= 287 J/kg/k
What is universal molar gas constant?
The gas constant (also known as the molar, universal, or ideal gas constant, normally indicated by the symbol R) is a physical constant which is used in many of the fundamental equations in the physical sciences, such as the ideal gas law and the Nernst equation. It is equivalent to the Boltzmann constant, but expressed in units of energy (i.e. the pressure-volume product) per kelvin per mole (rather than energy per kelvin per particle). The gas constant uses the same units as specific entropy.Its value is: : R = 8.314472(15) J · K-1 · mol-1The two digits in parentheses are the uncertainty (standard deviation) in the last two digits of the value. The gas constant occurs in the simplest equation of state, the ideal gas law, as follows: : PV = nRT = nRT / V = RT / Vmwhere: : P: is the absolute pressure : T: is absolute temperature : V: is the volume the gas occupies : n: is the amount of gas (the number of gas molecules, usually in moles) : Vm: is the molar volume
What is the Arrhenius equation?
It is an equation that relates the speed at which a chemical reaction progresses with the activation energy and the temperature of the reactants and products. k = A * e^(-Ea/(R*T)) Where k = velocity constant (different for each reaction) A = pre-exponential factor Ea = activation energy R = universal gas constant (=8,314J/molK) T = temperature
What is the difference between universal gas constant and characteristic gas constant?
The Universal gas constant is R is independent of the gas taken.. While the Characteristic gas constant depends on the mol. mass of the gas.... The Characteristic gas constant of a gas or a mixture of gases is given by the molar gas constant, divided by the molar mass (M) of the gas/mixture. R(Characteristic) = {R}/{M} Well,this is just the basic...u can relate them both to the Boltzmann constant.. Here are some of the standard values for both: Values of R Units 8.314 472(15) J K−1 mol−1 0.082057 46(14) L atm K−1 mol−1 RChar for dry air Units 287.058 J kg−1 K−1 ok,i guess this is it!Hope this clears it...
Who calculate the value of universal gas constant 'G'?
The universal gas constant is denoted by R = 8.314 J/kgK, (but not G which denotes the Gibbs free energy of a given reaction at given conditions.
The value of the gas constant is?
Values of general gas constant are: (value dependant on units) R = 0.08205746 [atm. ℓ.mol-1.K-1] R = 8.314472 [Pa.m3.mol-1.K-1 or J.mol-1.K-1] R = 1.99 [Cal.mol-1.K-1]
What is the Value of R(universal gas constant) and ratio of sp. heats of refrigerent R314a and R134a?
In SI units, the gas constant has a value of approximately 8.314 J / (mol x kelvin).
What is the constant in bowel's law?
Boyles law is Pv= k and refers to any mass of gas under observation. It is often stated as p1V1 = p2V2 In words :- the product of pressure and volume remain the same (constant) as you change pressure or volume in your experiment. The constant k in the equation is not a universal constant (like R the universal gas constant) just a constant for that particular experiment.
How can you derive the expression for calculation of the velocity of sound in a gas at temperature T asqrtYRT?
See the links below. Remember to distinguish where necessary between the universal gas constant R (joules per mole Kelvin) and the particular gas constant R (joules per kilogram Kelvin)
What are different NAME of constant r?
R may be the Rydberg constant or the gas constant.
Relationship of temperature and pressure?
The ideal gas law states P*V=n*R*T where P is the pressure of the gas, V is the volume of the gas, n is the amount of substance of gas (also known as number of moles), T is the temperature of the gas and R is the ideal, or universal, gas constant, equal to the product of Boltzmann's constant and Avogadro's constant.
Does the gas constant R vary with temperature?
No, the gas constant, or any constant, is constant meaning it doesn't change.
How was the gas law formulated?
The general gas law is:PV = nRT, where:* P is the pressure* V is the volume* n is the number of moles* R is universal constant of gases* T is the temperature
