Wind is the movement of air from an area of high pressure to an area of low pressure. In fact, wind exists because the sun unevenly heats the surface of the Earth. As hot air rises, cooler air ...

By the time the climber reaches the highest point of Mount Everest, the air pressure is only around 33,700 Pa approximately one third of the atmospheric pressure at sea level. Altitude sickness is ...

Low density components such as electrolytic capacitors have either air or fluids which are susceptible to compression under water and prone to damage. Since pressure tolerance is not part of most ...
