Kinetic particle model of matter — practice question

A gas produces pressure because its particles strike the walls of a container. Which statement about the gas particles is correct?

  • AThey experience a change in force, which results in a pressure equal to momentum $\times$ area.
  • BThey experience a change in force, which results in a pressure equal to $\frac{\text{momentum}}{\text{area}}$.
  • CThey experience a change in momentum, which results in a pressure equal to force $\times$ area.
  • DThey experience a change in momentum, which results in a pressure equal to $\frac{\text{force}}{\text{area}}$.
