Question

when gas particles collide with the walls of their container, the particles push on the walls. together, these forces cause gas pressure. gas pressure is what makes objects such as bike tires and beach balls feel firm when they are inflated. a gass pressure depends on both the total force exerted by its particles and the area that the force is spread over. the more force the particles exert over a given area, the higher the gas pressure. which of the following statements are true? select all that apply. a gass pressure is higher when its particles exert more force over a given area. gas particles push on the walls of their container. an inflated basketball feels firm because of gas pressure. gas pressure is caused by gas particles colliding with each other.

Explanation:

1. The text states "The more force the particles exert over a given area, the higher the gas pressure", so the first statement is true.
2. It is mentioned that "When gas particles collide with the walls of their container, the particles push on the walls", so the second statement is true.
3. Since "Gas pressure is what makes objects such as bike tires and beach balls feel firm when they are inflated", an inflated basketball (similar object) feels firm because of gas pressure, making the third statement true.
4. The text says gas pressure is caused by gas - particles colliding with the walls of the container, not with each other, so the fourth statement is false.

Answer:

A. A gas's pressure is higher when its particles exert more force over a given area.
B. Gas particles push on the walls of their container.
C. An inflated basketball feels firm because of gas pressure.
