Explain, in terms of the behaviour of molecules, how a gas exerts a pressure on the walls of its container. (4)

This question is 4 marks so you need to make at least 4 points.

These types of questions just require memorising the 4 points:

Lots of molecules collide with the walls.

The molecules change momentum as they collide with the walls.

Force is the rate of change of momentum.

Pressure = force/area.

Remember these 4 points and you'll get full marks for the question.

how do you calculate the charge of a neuclues compared to an ion?


A trolley of mass 0.75kg is running along a frictionless track at a constant speed of 0.7ms-1, as the trolley passes below a mass of 0.5kg the mass drops a short vertical distance onto the trolley. Calculate the new velocity of the trolley and mass.


What is meant by the doppler effect?


Is the excitation and de-excitation of an electron from the ground state (of an atom) due to the collision of another particle (e.g. electron) an elastic collision or an inelastic collision.
