What are the laws of Thermodynamics?

The laws of thermodynamics illustrate the physical quantities, that is, the energy, temperature, and entropy, which characterize thermodynamic systems at thermal equilibrium. The following are the laws of thermodynamics:

1. The first law of thermodynamics: With the passing of the energy in the form of heat, work, or matter within or outside of a system, there is a change in the internal energy of the system in accordance with the law of conservation of energy.

2. The second law of thermodynamics: The sum of the entropies of the associating thermodynamic systems increases in a natural thermodynamic process.

3. The third law of thermodynamics: The system's entropy becomes a constant value when the temperature inclines towards absolute zero.
