Particle Motion In Gases (GCSE Physics)

Which factor most directly reduces the mean free path of particles in a gas?

If two gases at the same temperature have different molecular masses, how do their root mean square speeds compare?

Which explanation best describes gas pressure on the walls of a container?

How does adding an inert gas (that does not react) to a container at constant volume affect the partial pressure of the original gas?

Which statement correctly links rms (root mean square) speed, temperature T (in kelvin), and particle mass m for an ideal gas (qualitative Year 10 form)?

What will happen to the pressure reading of a tyre if its temperature increases while volume and amount of gas remain constant?

Why does increasing temperature cause a gas to exert more pressure on its container (if volume is fixed)?

A sealed syringe contains trapped air. The plunger is pushed slowly reducing volume; temperature is kept constant. What happens to the spacing between particles and the frequency of collisions?

When a gas is compressed quickly, the temperature rises. What happens to the mean kinetic energy of the particles during this process?

What happens to the frequency of particle collisions with the walls when the density of a gas in a sealed container is increased?

Which quantity increases when the temperature of a fixed mass of gas increases at constant volume?
