10. If the number of particles in the left box above were doubled, what would happen to the pressure of the gas? Explain.

A. The pressure of the gas on the left would decrease because the number of collisions would also

decrease.

B. The pressure of the gas on the left stay the same because the number of collisions would also be the

same

C. The pressure of the gas on the left would decrease because the number of collisions would increase.

D. The pressure of the gas on the left would double because the number of collisions would also double.

D. The pressure of the gas on the left would double because the number of collisions would also double.

Explanation:

According to Boyle’s law, the pressure of a gas is inversely proportional to its volume.

As the number of particles was doubled in the left box, the particles have less space for movement as the volume occupied by gas particles has decreased and it will lead to the collision of gas particles with the walls of the container.

As the volume decreases as gas particles were doubled and so the pressure of the gas on the left would double.

Hence, the correct answer is "D. The pressure of the gas on the left would double because the number of collisions would also double."
