Laws of Thermodynamics

The state of entropy of the entire universe, as an isolated system, will always increase over time.

• First Law of Thermodynamics

• Second Law of Thermodynamics

• Third Law of Thermodynamics

• Zeroth Law of Thermodynamics

All thermodynamics can be expressed in terms of four quantities, EXCEPT:

• Temperature

• Internal Energy

• Entropy

• Luminous Intensity

Energy can be converted from one form to another with the interaction of heat, work and internal energy, but it cannot be created nor destroyed, under any circumstances.

What is proportional to internal energy?

• Temperature

• Heat

• Entropy

• External Energy

If system A is in thermal equilibrium with system C and system B is also in thermal equilibrium with system C, system A and system B are in thermal equilibrium with each other.
