B. The average speed of the nitrogen molecules is the same as the average speed of the argon molecules.
The given parameters;
- mass of the nitrogen = 14 g
- mass of the argon = 20 g
The density of an object is defined as mass per unit volume. The gas with greater mass will have the greater density.
The average speed of the gases decreases with increase in mass. The gas with smaller mass will have the greatest speed.
The average kinetic energy of the gases increases with increase in speed.
The number of moles, and volume of gases is different.
Thus, the only incorrect statement in the given options is B.
"The average speed of the nitrogen molecules is the same as the average speed of the argon molecules".
