Question

If gas particles start colliding with the walls of their metallic container with increased force, what is their direct effect?
lower gas pressure
higher gas pressure
lower volume of gas
higher volume of gas

Answer 1

A metal container will not expand, so the volume will not change. This eliminates 2 of the options.

\(\sf Pressure=\dfrac{Force}{Area}\)

Say the force initially was 100 N, and it increased to 200 N.

\(\sf Pressure=\dfrac{100~N}{1~m^2}=100~Pa\)

\(\sf Pressure=\dfrac{200~N}{1~m^2}=200~Pa\)

An increased of force in the collisions with the container walls increased the pressure.
