PHYSOCS - kinetic model of matter

Boyle’s law

• temp constant

• volume of container change

• volume of container decrease, particles collide more frequently with wall.

• average velocity of particles remain the same

• average force exerted on wall increases, since P = F/A , pressure increase

Charles’ law

• temp changes

• volume of container constant

• temp increases, average K.E store of particles increase

• Average velocities of particles increase.

• collide with wall more frequently, and vigorously

• Force exerted on wall causes volume to increase.

• After the space expands, freq of collisions between particles and wall decreases.

• pressure remains constant

Gay - Lussac’s law

• volume unchanged, container fixed

• vary temp

• temp increase, average K.E store of particles increase

• Average velocity of particles increase. Particles collie with wall more frequently and vigorously.

• Avg. force exerted on wall increase. Since, P = F/A , pressure increase
