Oxygen, the colorless and odorless gas that is essential to the survival of humans and other living organisms, is estimated to make up around 21% of Earth's atmosphere. While the primary properties of ...

Abstract: Pressure vessels are closed structures containing liquids or gases under pressure. Familiar examples include fuel tanks, pipes, and pressurized cabins in aircraft and space vehicles. When ...

The pressure caused by a column of liquid can be calculated using the equation: pressure = height of column × density of the liquid × gravitational field strength The density of water is 1,000 kg/m 3.

A new discovery has reshaped our understanding of PCR chip technology: water vapor, not air expansion, is the primary culprit behind bubble formation in polydimethylsiloxane (PDMS)-based chips. This ...

The particles in a gas are moving very quickly in random directions. The speeds of the particles vary but, on average, they move quicker than they do in liquids or solids. This means that it does not ...
