Voici une ventilation:
* solides: The particles in a solid are tightly packed and vibrate in fixed positions. Adding thermal energy makes them vibrate faster and with greater amplitude.
* Liquides: The particles in a liquid are more loosely packed than in a solid and can move around. Adding thermal energy increases the speed and freedom of movement of the particles.
* gaz: The particles in a gas are far apart and move freely. Adding thermal energy makes them move faster and collide more frequently.
en résumé: Thermal energy is essentially the energy associated with the random motion of particles within a substance. Adding thermal energy increases the kinetic energy of these particles, leading to faster movement and/or greater vibrations.
