Question 2

According to the particle model, why does the pressure of a gas increase when the volume of its container decreases? Give a real-life example to support your answer.

Accepted Answer

As the volume decreases, particles become closer, increasing collisions and pressure.

Answer

As the volume decreases, particles move faster and collide more often, increasing pressure.

Answer

As the volume decreases, gas temperature rises, leading to increased pressure.

Answer

As the volume decreases, gas particles escape, reducing pressure.
