Speed of molecular movement

WebAccording to Kinetic Molecular Theory, gaseous particles are in a state of constant random motion; individual particles move at different speeds, constantly colliding and changing directions. We use velocity to describe the movement of gas particles, thereby taking into account both speed and direction. WebThe Kinetic-Molecular Theory Explains the Behavior of Gases, Part II. According to Graham’s law, the molecules of a gas are in rapid motion and the molecules themselves are small. The average distance between the molecules of a gas is …

WebAug 31, 2024 · The O 2 molecules in air at room temperature move about 50 percent faster than jet planes, and H 2 molecules are nearly 4 times speedier yet. Of course an O 2 molecule would take a lot longer to get from New York to Chicago than a jet would. Gas molecules never go far in a straight line before colliding with other molecules. WebJan 12, 2016 · 1 At sea level the speed of sound is 760mph, but at altitudes like the Concorde would fly at (55,000ft) the sound barrier is at 660mph, so 1000th slower.
