Gas constant

The gas constant, often represented by the letter R, is a fundamental value used in physics and chemistry to describe the behavior of gases. It appears in equations that relate the pressure, volume, temperature, and amount of gas. Essentially, it helps scientists calculate how gases will behave under different conditions. The gas constant has a specific numerical value (approximately 8.314 J/(mol·K)), which is used in equations like the ideal gas law, helping to predict how gases expand, contract, or change when heated or compressed. Understanding R is crucial for studying thermodynamics and gas-related processes.
