Ideal gas equation or perfect gas equation represents the relationship between the pressure (p), density (𝜌), temperature (T), and the gas constant (R) for an ideal gas.
- p: Pressure of the gas in N/m^2.
- 𝜌: Density of the gas in kg/m³.
- R: The specific gas constant for the particular gas being considered in J/(kg·K)
- T: Absolute temperature of the gas in Kelvin, K.
