Particle Motion In Gases (GCSE Physics)

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?

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

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)?

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

Which best explains Brownian motion observed for small pollen grains in water as evidence for particle motion?

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

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

Which practical observation supports the particle model explanation for gas pressure?

When comparing two samples of the same gas, one at 300 K and one at 600 K, both at equal pressure, how do their average kinetic energies compare?

What is the main reason gas diffusion is faster in helium than in air at the same temperature?

Which statement is a correct interpretation of absolute zero (0 K)?
