2024年7月16日 · The gas constant or R is an essential constant in the ideal gas law. Discover the definition and value of the gas constant.

2021年2月11日 · The gas constant (R) is a proportionality constant used in the ideal gas law and Nernst equation. It’s also called the ideal gas constant, universal gas constant, or molar gas …

Definition of the universal gas constant (R) frequently used in ideal gas equations, along with gas constant values for different units.

The induvidual gas constant, R, for a gas can be calculated from the universal gas constant, R u ( given in several units below), and the gas molecular weight, M gas : R = R u / M gas (1)
