The second law of thermodynamics introduces the concept of ___________.
Entropy
There are four laws of thermodynamics:
Zeroeth Law of Thermodynamics - If two thermodynamic systems are each in thermal equilibrium with a third system, then they are in thermal equilibrium with each other.
First Law of Thermodynamics - Energy cannot be created or destroyed; it can only change forms. In any process, the total energy of the universe remains constant.
The net heat supplied to the system for a thermodynamic cycle is equal to the net work done by the system.
δQ = ΔU + δW
Second Law of Thermodynamics - For any isolated system that is not in equilibrium, entropy tends to increase over time, and it reaches its maximum value at equilibrium.
ΔS = ΔQ/T
ΔStotal = ΔSsystem + ΔSsurroundings
The second law of thermodynamics introduces the concept of entropy.
Third Law of Thermodynamics - As the temperature approaches absolute zero, the entropy of a system approaches a stable minimum.
ΔST = 0K = 0
