Principles of thermodynamics
- According to the first law of thermodynamics, “energy can be neither created nor destroyed, but only changed from one form to another. Living organisms thus cannot consume or use up energy; they can only transform one form of energy into another”.
- The second law of thermodynamics tells us that “in any energy transformation, not all energy is transformed, and some energy will be lost simply because no transformations are 100%
- It also states that all physical and chemical processes always precede with an increase in the disorder or randomness of the world i. e. its entropy”.
- Third law of thermodynamics: The entropy of a system approaches a constant value as the temperature approaches zero.
