How motion of molecules cause pressure exerted by gas
Explain how molecular movement causes the pressure exerted by a gas. 9702_w24_qp_42-Q4(b)
- Molecules collide with walls of container
- Momentum of molecule changes during collision with wall
- According to Newton’s Second Law, change in momentum is caused by force on molecule by wall
- According to Newton’s Third Law, molecule experiences force from wall so molecule exerts force on wall
- Many molecules exerting force across the area of the wall leads to pressure.
