Independent
not influenced or controlled by others; acting autonomously.
Average Kinetic Energy
The mean energy possessed by the particles of a substance due to their random motions, directly related to temperature.
Kinetic-Molecular Theory
A theory that explains the behavior of gases, stating that gas particles are in constant motion and that this motion has consequences for properties like pressure, volume, and temperature.
Temperature
A measure of the average kinetic energy of the particles in a sample of matter, expressed in degrees Celsius, Fahrenheit, or Kelvin.
