Because the air has mass, it also makes the air inertial, so that the density of the spatially distributed molecules changes very little. In this way, the larger the particles, the smaller the distance between the molecules. That is, the temperature rises and the air pressure rises, causing the air gap to become smaller. The smaller the gap, the shorter the distance that sound waves travel, so the speed of sound propagation increases. |
