*The density of compressed air varies with pressure and temperature. At standard conditions (1 atm, 0°C), it’s approximately 1.225 kg/m³. As pressure or temperature increases, density changes accordingly. For instance, at 100 kPa and 25°C, it’s around 1.164 kg/m³, while at 500 kPa and 60°C, it’s about 4.728 kg/m³. These values are approximate and depend on specific conditions.*
