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 depends on the total force exerted by its particles on the container walls. gas pressure is caused by gas particles colliding with each other. because of gas pressure, a balloon feels firm when it is filled with helium gas. gas particles pull on the walls of their container.

Explanation:

• The text states that a gas's pressure depends on the total force exerted by its particles (so the first statement is true).
• It says gas pressure is caused by gas - particle collision with container walls, not with each other (so the second statement is false).
• It mentions that gas pressure makes objects like bike tires firm when inflated, so a balloon filled with helium (a gas) feeling firm due to gas pressure is in line (third statement is true).
• The text says particles push on the walls, not pull (fourth statement is false).

Answer:

A. A gas's pressure depends on the total force exerted by its particles on the container walls.
C. Because of gas pressure, a balloon feels firm when it is filled with helium gas.
