Below are sample questions representative of the exercises included on this worksheet and related 8.25 Gas Properties and Pressure (Qualitative) skill assessments:

Problem 1Difficulty: Mastery

Compared with the initial state at pressure P, which statement is best about particle motion and spacing in the final state?

AParticles move more slowly and are farther apart, restoring pressure P.

BParticle motion and spacing must be unchanged because pressure is the same.

CParticles move more slowly (lower temperature), but they are packed into a smaller volume, increasing collision frequency enough to restore pressure P.

DParticles move faster, but they are farther apart, restoring pressure P.

Solution & Explanation:Cooling lowers particle speed and collision force. To regain the same pressure, volume must decrease so collision frequency increases. Same pressure can result from different combinations of speed and spacing.

Problem 2Difficulty: Mastery

In terms of particle collisions," why is the pressure higher in the second container?,A. Particles change into a different state that creates pressure. | B. Particles have lower kinetic energy

Solution & Explanation:increasing the average force. | D. Particles collide less often

Problem 3Difficulty: Mastery

Which action could do that while keeping volume fixed?

AStir the gas, because stirring stops collisions.

BAdd more gas particles, because more particles reduces collisions with the walls.

CLower the temperature, because slower particles strike the walls less often and with less force.

DChange the container’s shape while keeping temperature the same.

Solution & Explanation:With volume fixed, the main way to reduce wall collision rate/force is to reduce particle kinetic energy by cooling. Adding particles increases collisions; changing shape alone doesn’t lower average collisions at equilibrium.
