... The first law of thermodynamics states the equivalence of heat and work and reaffirms the principle of conservation of energy. The second law states that heat does not of itself pass from a cooler to a hotter body. Another, equivalent, formulation of the second law is that the entropy of a closed sy ...

The Clausius statement of the second law of thermodynamics says that in any thermodynamics process, reversible or irreversible, the total entropy of the universe must either remain constant (reversible process) or increase (irreversible process). Thus, if in a thermodynamics process, the entropy of ...

Introduction to Thermodynamics
... First Law of Thermodynamics Energy is a property of any system, and changes in this property can be deduced from the conservation-of-energy principle. The work needed to change an adiabatic system from one specified state to another is the same however the work is done (mountain climbing analogy). ...
