Laws of Thermodynamics
Laws of Thermodynamics
The Laws of Thermodynamics are fundamental principles that describe the behavior of energy and heat in natural systems. They are essential in the fields of physics, chemistry, and engineering.
Pronunciation
Laws of Thermodynamics: /lɔːz ɒv θɜːrməʊdaɪˈnamɪks/
Etymology
The term "Thermodynamics" comes from the Greek words "therme" meaning heat and "dynamis" meaning power. The "Laws of Thermodynamics" were so named because they describe the fundamental rules governing the transfer and transformation of heat energy.
First Law of Thermodynamics
The First Law of Thermodynamics, also known as the Law of Energy Conservation, states that energy cannot be created or destroyed, only transferred or changed from one form to another.
Second Law of Thermodynamics
The Second Law of Thermodynamics states that the total entropy, or disorder, of an isolated system can never decrease over time.
Third Law of Thermodynamics
The Third Law of Thermodynamics states that the entropy of a system approaches a constant value as the temperature approaches absolute zero.
Zeroth Law of Thermodynamics
The Zeroth Law of Thermodynamics states that if two systems are each in thermal equilibrium with a third, they are in thermal equilibrium with each other.
