Answer:
Well ads I remember, the motion of the gas particles is random and in a straight-line. A sample of gas is contained in a closed rigid cylinder.
And here is what I found too -
According to Kinetic Molecular Theory, gaseous particles are in a state of constant random motion; individual particles move at different speeds, constantly colliding and changing directions. We use velocity to describe the movement of gas particles, thereby taking into account both speed and direction.
A - 12
The amount of protons in a specific element do not change, for if the protons change, then the element themselves change. Therefore, no matter what, if the question specifies the element (i.e. Carbon) then the amount of protons will remain the same as seen on the periodic table.
Hope this helps!
