Thermodynamics

Thermodynamics. a system: Some portion of the universe that you wish to study. The surroundings: The adjacent part of the universe outside the system. Changes in a system are associated with the transfer of energy. Natural systems tend toward states of minimum energy. Energy States.

Thermodynamics

Thermodynamics. Temperature. Temperature is the measurement of the average kinetic energy of material. Atoms move around and collide with the thermometer and exchange its energy causing the thermometer to go up. Three units of measuring temperature Fahrenheit (Used only in the US)

2 nd Law of Thermodynamics

2 nd Law of Thermodynamics. All things tend toward entropy (randomness). Molecules move (diffuse) from an area of high concentration to areas of low concentration. Eventually, molecules become randomly distributed unless acted on by something else. Osmosis.
