The specific gas constant () has different values depending on the units used for pressure, volume, and temperature. The value of is commonly expressed in different units to match the units of other quantities in various equations. It plays a crucial role in thermodynamics and fluid dynamics, providing a bridge between macroscopic properties like pressure, volume, and temperature and the microscopic behavior of gas molecules.
- is the specific heat capacity at constant pressure
- is the specific heat capacity at constant volume
- is the gas constant for a particular substance.
