R (gas constant)

The gas constant, symbolized as R, is a fundamental number used in chemistry and physics to relate the energy of gases to their temperature and amount. It connects concepts like pressure, volume, temperature, and moles of gas in the ideal gas law (PV = nRT). Essentially, R helps scientists calculate and predict how gases behave under different conditions. Its value is approximately 8.314 Joules per mole per Kelvin (J/mol·K), serving as a bridge between energy and temperature for gases, and allowing precise understanding and application of gas laws across scientific and engineering contexts.
