WebJan 7, 2024 · Decreasing pressure causes the air in a diver's air spaces to expand. The air spaces in their ears and lungs experience a positive pressure as they become overfull of air, leading to pulmonary barotrauma or a reverse block. In a worst-case scenario, this could burst a diver's lungs or eardrums. WebExamples to show that air exerts pressure:1. When air is pumped inside a balloon, it expands in size. This shows that the air inside exerts pressure on the walls of the balloon. 2. A sealed packet of chips swells up in the mountains. This is because the atmospheric pressure at higher altitudes is less whereas the packet is filled with gas at normal …
