Step 2
(b)(i) Explain how the particles in the gas exert a pressure on the syringe.
Answer
Gas particles exert pressure on the syringe walls by colliding with them. Each collision exerts a small force, and when many particles collide with the walls of the syringe, the collective force results in a measurable pressure. The pressure is proportional to the frequency and force of the particles' collisions against the syringe walls.
