The air would be so thin that even the best climber would have no choice but to use supplemental oxygen. Why? Because of the many factors which affect atmospheric pressure. Pioneering scientists ...

Understanding atmospheric pressure is vital, newsroom meteorologist Justin Ballard said, because those giant H’s and L’s representing high and low air pressure systems on a weather map are ...

Short demo: The fan in a vacuum pushes air out, creating a system of low pressure. This in turn creates a system of low pressure within the bag, allowing for an entertaining demonstration of the power ...

The freeze last week has a weather term for it that was coined by a Texas A&M scientist back in 1976. It's called the ...

There are lots of great air pressure demonstrations around, but a leaky water bottle is one of the simplest. It looks impressive and costs almost nothing.

Air molecules colliding with a surface cause atmospheric pressure. Atmospheric pressure at sea level is about 101,000 Pa (101 kPa) but just 27,000 Pa (27 kPa) at the cruising altitude of a ...
