Acontainer of gas molecules is at a pressure of 2 atm and has a mass density of 1.7 grams per liter. all of the molecules in the container are diatomic nitrogen molecules with an atomic weight of 28 grams per mole. what is the average speed of the nitrogen molecules in the container? here we define the average speed as the root-mean-square velocity (rms velocity = vrms) of the center of mass of the molecule.

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
