Kinetic Particle Model Of Matter (continued)

Gbogbo ọrọ náà

Everything around you is made of countless tiny particles in constant motion. This single idea, the kinetic particle model, explains why solids hold their shape, why gases push on their containers, and why a balloon shrinks in the cold. It even has visible evidence you can watch under a microscope.

In this lesson you will picture the arrangement and motion of particles in solids, liquids and gases, link temperature to particle energy down to absolute zero, explain gas pressure and Brownian motion in terms of collisions, and use \(pV=\text{constant}\) to predict how a gas responds to a change in volume.

Ebumnobi

  1. [Supplement] Describe qualitatively, in terms of particles, the effect on the pressure of a fixed mass of gas of: (a) a change of temperature at constant volume (b) a change of volume at constant temperature

The kinetic particle model is one of the most powerful ideas in physics: from it you can explain states of matter, temperature, pressure, expansion and the behaviour of gases, all from the picture of moving particles. It also gives examiners endless ways to ask 'explain in terms of particles', so the reasoning here is worth a great many marks.
