WebWe can decrease the weight per particle. Air is composed of 77% nitrogen, 21% oxygen and 2% other gases by weight. The density of air at room temperature and atmospheric pressure is approximately 1.3 kg/m 3. If we replace the air with Helium gas at the same temperature, the same particle density will yield the same pressure. WebFor air at STP (0 °C and 1 atm), γ = 1.40, and v = √ ( (1.40 × 8.314 J/mol·K ×273.16 K)/ (2.8967 × 10 -2 kg/mol)) = 331 m/s. If we call room temperature 298 K, the speed of sound works out to 346 m/s. For helium, of course, both γ and M are different. γ = 1.67, and M = 4.003 × 10 -3 kg/mol.

WebThe density of air is calculated using the ideal gas equation together with the ideal gas constant. The density of a liquid can be expressed as Ρ h20 is the nominal density of water. The density of air refers to the mass per unit volume of atmospheric gases. Density is mass divided volume d = m v.
