Physics Chapter 8: Kinetic Particle Model - Coggle Diagram

- - - - when the volume of air is halved, the number of molecules per unit volume DOUBLES, frequency of collisions between molecules and walls doubles, the pressure doubles as a result, pressure of a fixed mass of gas is INVERSELY PROPORTIONAL to volume at constant temperature
    - - when the temperature increases, the volume of gas increases as well, when the gas is heated, gas molecules move at higher average speeds, this leads to more frequent and forceful collisions between gas molecules and the wall of the container, pressure exerted is increased, to keep pressure constant, the gas expands to reduce frequency of collisions, this shows that volume of a fixed mass of gas is proportional to its thermodynamic temperature at constant pressure
    - - as the temperature increases, the gas molecules have higher average speeds, this makes more frequent and forceful collisions with the wall of the container, this increases the amount of pressure exerted as a result, this shows that the pressure of gas is PROPORTIONAL to its thermodynamic temperature at constant volume
- - - - temperature and Brownian motion, as the temperature increases, the kinetic energy of particles increases and the impact of air molecules on smoke particles increases, smoke particles move faster and change direction more frequently
