WebJan 28, 2014 · If they hit the surface of the balloon straight on (at a 90 ° angle), they exert their maximum force. If they hit the surface at an angle less than 90 °, they exert a smaller force. The sum of all these forces causes the pressure, p, that is exerted by the gas. The diagram above represents a balloon containing molecules of a gas (the red dots). WebThe pressure exerted by the gas on each wall is simply the force divided by the area of a wall. Rearranging things a little gives: This equation has many of the same variables as the ideal gas law, PV = NkT. This is a very important result, because it tells us something fundamental about temperature.

"WebLet's examine proportional factors that we have. 1.) The attractive force is proportional to the density of molecules (the more molecules we have, the stronger the force), hence proportional to n/V. 2.) On the same time not all molecules experience the same attractive forces. As it was said in the video, the attractive forces between the ... " - Force exerted by gas molecules
