Question

if gas particles start colliding with the walls of their metallic container with increased force, what is their direct effect?

higher gas pressure
lower gas pressure
higher volume of gas
lower volume of gas

Explanation:

Define gas pressure microscopically

Gas pressure is defined as the average force exerted by gas particles per unit area of the container walls during collisions.

Analyze the effect of increased force

If gas particles collide with the walls of their metallic (rigid) container with increased force, the total force exerted on the walls increases. Since pressure is force divided by area \(P = \frac{F}{A}\), an increase in force directly results in a higher gas pressure.

Evaluate the options

• "higher gas pressure": Correct, as increased collision force directly increases pressure.
• "lower gas pressure": Incorrect, as force and pressure are directly proportional.
• "higher volume of gas" / "lower volume of gas": Incorrect, because a metallic container is rigid, meaning its volume remains constant.

Answer:

• higher gas pressure (Correct answer)
• lower gas pressure
• higher volume of gas
• lower volume of gas
