Gas constant - Wikipedia
The molar gas constant (also known as the gas constant, universal gas constant, or ideal gas constant) is denoted by the symbol R or R. It is the molar equivalent to the Boltzmann constant, expressed in units of energy per temperature increment per amount of substance, rather than energy per temperature increment per particle.
Universal and Individual Gas Constants - The Engineering ToolBox
Individual gas constants for the most common gases. The Universal and Individual Gas Constants are known from the Ideal Gas Law. The Individual Gas Constant depends on the particular gas and is related to the molecular weight of the gas. The value is independent of temperature.

Universal gas constant | Definition, Value, Units, & Facts | Britannica
2025年1月14日 · Universal gas constant (R), fundamental physical constant arising in the formulation of the ideal gas law. The constant is the same for all gases, provided that the mass of gas being compared is one mole, or one molecular weight in grams. The value of R is 8.314462618 joules per kelvin per mole.
Gas Constant - Definition, Formula, Value, Gas Constant In …
The gas constant is a physical constant denoted by R and is expressed in terms of units of energy per temperature increment per mole. It is also known as the ideal gas constant or molar gas constant or universal gas constant.
Value of Universal Gas Constant: Formula, Units, and Dimension
2024年1月3日 · The Universal Gas Constant, also known as the molar gas constant, is a physical constant denoted by the symbol R. It is expressed in units of energy per temperature increment per amount of substance and is the molar equivalent to the Boltzmann constant.
The universal gas constant (Ru) is, as its name implies, universal, i.e., the same regardless of the gas being considered. The ideal gas law in terms of Ru is P V nR u T , where P is the absolute pressure of the gas, V is the volume occupied by the gas, n is the number of mols of the gas, and T is the absolute temperature of the gas.
Universal Gas Constant - (Intro to Chemistry) - Fiveable
The universal gas constant, denoted as R, is a fundamental physical constant that represents the proportionality between the pressure, volume, amount of substance, and absolute temperature of an ideal gas.
Universal Gas Constant - Scienceeureka.com
When one gram-molecule or one mole of an ideal gas is taken, the constant is written as R. As per Avogadro’s law, at the same temperature and pressure, the volume of 1 gram-molecule of any gas is the same. Therefore, the value of the constant R, for all ideal gases is the same. Hence, R is called the Univeral Gas Constant or Molar Gas Constant.
