"the molecules stay in contact with the solid body"...????????????? Why? It's what gases do. The particles are constantly bouncing away from each other. This is pretty simple physics - something that should almost be intuitive. If you have a cylinder of gas with an air-tight piston and pull back on the piston and double the size of the volume do you seriously think the gas will not expand into the other half as fast as it can to try and stay in contact with the piston? If you are having this much trouble on a basic concept of gases, then I see no value in you or anyone else investing time in dealing with your questions, which you chose to post to an inappropriate newsgroup anyway. Grumble. Now I recall why I had established a personal policy to stay away from discussions of aerodynamics on this newsgroup: futility avoidance. |
