In addition to its role in nature, gas pressure is also a key factor in many human-made technologies, such as engines, refrigeration systems, and scuba diving equipment. For example, internal combustion engines rely on the expansion of gases to generate mechanical work, with pressure playing a critical role in driving pistons and rotating crankshafts. Refrigeration systems use changes in gas pressure to transfer heat from one area to another, enabling the cooling of refrigerated spaces. Scuba diving equipment utilizes gas pressure to regulate the air supply to divers at different depths, ensuring their safety and comfort underwater.
