Thermodynamics law is a set of principles that govern the behavior of energy in a system.

• There are four laws of thermodynamics

• The first law states that energy cannot be created or destroyed, only tran...read more

Helmholtz free energy: F = U – TS

Gibbs Free Energy: G = U + PV – TS

Internal Energy: U=∫TdS−PdV+∑iμidNi

Enthalpy: H = U + PV

1st Law of Thermodynamics - Energy cannot be created or destroyed. 2nd Law of Thermodynamics - For a spontaneous process, the entropy of the universe increases.

The laws of thermodynamics define a group of physical quantities, such as temperature, energy, and entropy, that characterize thermodynamic systems in thermodynamic equilibrium. The laws also use various parameters for thermodynamic processes, such as thermodynamic work and heat, and establish relationships between them. They state empirical facts that form a basis of precluding the possibility of certain phenomena, such as perpetual motion. In addition to their use in thermodynamics, they are important fundamental laws of physics in general, and are applicable in other natural sciences.
