Nov 21, 2022 · Like water, air is a fluid (the name we give to liquids and gases that can easily move, or flow) and, generally speaking, most fluids behave the same way. If you want to speed quickly through the air, you're better off in a long, thin vehicle—something like a plane or a train—that creates as little disturbance as possible: planes and trains are tube-shaped for exactly the same reason that ...
The air entering low pressure area on top of the wing speeds up. The air entering high pressure area on bottom slows down. That is why air on top moves faster. That results in deflection of the air downwards, which is required for generation of lift due to conservation of momentum (which is a true law of physics).
Oct 10, 2023 · At higher temperatures, therefore, the molecules of a gas move more rapidly than at lower temperatures, and v p increases. The rms speed and the average speed do not differ greatly (typically by less than 10%). The distinction is important, however, because the rms speed is the speed of a gas particle that has average kinetic energy.
Amontons' Law (PT) The last postulate of the kinetic molecular theory states that the average kinetic energy of a gas particle depends only on the temperature of the gas. Thus, the average kinetic energy of the gas particles increases as the gas becomes warmer. Because the mass of these particles is constant, their kinetic energy can only ...
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 and solids. This means that it does ...
Jun 25, 2023 · 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.
