Two balloons are at the same temperature and pressure. One contains 14 g of nitrogen and the other contains 20.0 g of argon. Pick the false statement from the following list:
A. The density of the nitrogen sample is less than the density of the argon sample.
B. The average speed of the nitrogen molecules is the same as the average speed of the argon molecules.
C. The average kinetic energy of the nitrogen molecules is the same as the average kinetic energy of the argon molecules.
D. The volume of the nitrogen container is the same as the volume of the argon container.
E. The number of molecules in the nitrogen container is the same as the number of atoms in the argon container.
Answer (3)
b is the answer to the question
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".

The false statement is B: "The average speed of the nitrogen molecules is the same as the average speed of the argon molecules," because nitrogen, being lighter, moves faster than argon at the same temperature. All other statements are true based on properties of gases at the same temperature and pressure. Therefore, the key takeaway is relating molecular mass to speed in gases.
