Question

Which quantity is most closely related to the speed of gas particles?
the temperature of the gas
the number of molecules in the gas
the density of the gas
the total volume of the gas

Answer 1

well in all honesty all three affect the speed of the gas I'm assuming that is escaping a container of some type but the one that is the temperature because the hotter it is the more the gas expands and thusly the particlces have more room to move freely vis versa the colder the more it condenses the less room the particles have to move around however the question should state more on the constants becuase with the question as is all three affect the speed of the gas escaping and so this answer is not a one hundred percent garruntee if there were more information on the constant then the answer could better be rooted out.
