Ordinary air is generally considered a homogeneous mixture of gases, primarily nitrogen, oxygen, and trace amounts of other gases. While the composition remains consistent over short periods, local variations can occur due to pollution, humidity, and temperature changes. However, these variations do not make air heterogeneous in the strict sense; it remains uniform at a macroscopic level. Thus, for practical purposes, air is treated as a homogeneous mixture day after day.
