Density is a fundamental physical property that quantifies the mass of a substance per unit volume. It is a measure of how much matter (mass) is packed within a given amount of space (volume). The below equation is the Ideal gas law for the density (ρ) of a gas. The ideal gas law is a fundamental equation in thermodynamics that relates the pressure (P), volume (V), temperature (T), and molar gas constant (R) of an ideal gas.
- ρ (rho): Density of the gas
- P: Pressure of the gas
- R: Molar gas constant
- T: Absolute temperature of the gas
