Which of the options best describes what is happening to the pressure when volume is decreased?

• As the volume is decreased the particles are closer together causing the pressure to decrease

• As the volume is decreased the particles are closer together causing the pressure to increase

• As the volume is decreased the particles are farther apart causing the pressure to decrease

• As the volume is decreased the particles are farther apart causing the pressure to increase

Refer to the image.

Which of the options best describes what is happening to the volume of the balloon when the container was heated?

• As the temperature increase, the particles collide more with the container so the volume will expand (get larger) to keep the pressure constant

• As the temperature increase, the particles collide more with the container so the volume will contract (get smaller) to keep the pressure constant

• As the temperature increase, the particles collide less with the container so the volume will expand (get larger) to keep the pressure constant

• As the temperature increase, the particles collide less with the container so the volume will contract (get smaller) to keep the pressure constant

Refer to the image.

Which of the options best describes what is happening to the pressure of the container when the container was heated?

• As the temperature increases, the particles move slower and collide less, causing the pressure to increase

• As the temperature increases, the particles move faster and collide more, causing the pressure to decrease

• As the temperature increases, the particles move slower and collide less, causing the pressure to decrease

• As the temperature increase, the particles move faster and collide more, causing the pressure to increases

Refer to the image.

Which of the options best describes what is happening to the pressure of the container all of the gases are mixed together?

• When all of the gases are combined, there will be more collisions between the particles causing the pressure to increase

• When all of the gases are combined, there will be more collisions between the particles causing the pressure to decrease

• When all of the gases are combined, there will be less collisions between the particles causing the pressure to increase

• When all of the gases are combined, there will be less collisions between the particles causing the pressure to decrease
