Transcription: We see how the depression affects a volume of air. If you understand that with a flexible and inflexible air, the air and the volume are completely proportional to the pressure. For example, with a pressure of 2.5 m or 10 m, 23ps, the volume is limited from what it was in the surface. At 3.5 m or 20 m, 76ps is a pressure, and yes, the same. The idea is to expand when two hours and the pressure is 10 minutes. If the pressure reduces to the height of 10 meters, 23 p.m. at the super-fast, the volume of the air is double. If you think of the volume in the air and the distance, during the time, you ...
