Atoms and molecules are perpetually in motion from "summary" of Physics 11 by British Columbia. Schools Department. Curriculum Development Branch
Atoms and molecules are perpetually in motion. This perpetual motion is a fundamental characteristic of all matter in the universe. Even at temperatures close to absolute zero, atoms and molecules continue to vibrate and move. This constant motion is due to the kinetic energy possessed by atoms and molecules. The higher the temperature, the greater the kinetic energy, and thus the faster the motion of the particles. At absolute zero, when the temperature is at its lowest possible point, particles would theoretically stop moving altogether. However, reaching absolute zero is not physically achievable. The motion of atoms and molecules has important implications for the behavior of matter. For example, in a gas, the constant motion of particles leads to collisions between them. These collisions are ...
