Definitions:

Closed Container

A system where no matter is allowed to enter or leave, though energy transfer may still occur.

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.
