Watch this fascinating demonstration of air pressure at work. Notice how the egg vibrates as the heated air escapes around it, and how it gets smoothly pushed into the bottle by atmospheric pressure.

Why? Because of the many factors which affect atmospheric pressure. Pioneering scientists discovered atmospheric pressure (also known as barometric or air pressure) in the 17th century ...

The film discusses the concepts of boiling point and pressure ... equals atmospheric pressure, and demonstrates how changes in pressure affect the boiling point of water through experiments.

Because salt has been detected on Mars, it is likely that Martian mudflows are also salty, much like Earth’s mud volcanoes, ...

So researchers designed an experiment to compress hydrogen and helium, reaching pressures nearly 2 million times Earth’s atmospheric pressure and temperatures of thousands of degrees Celsius ...

1643: Evangelista Torricelli conducts Berti's experiment with mercury instead of water. This leads to the invention of the barometer, which measures atmospheric pressure (a measure of the pressure ...

At Southern Methodist University, geophysicist Stephen Arrowsmith set up barometers across campus to measure changes in ...
