Glossary of "Life (9th ed.)" by Sadava et al. (2011)
- The principle that when energy is converted from one form to another, some of that energy becomes unavailable for doing work.
Glossary of "Environmental Science: Earth as a Living Planet (2nd ed.)" by Botkin & Keller (1998)
- A fundamental principle of energy that states that energy always tends to go from a more usable (higher quality) form to a less usable (lower quality) form. When we say that energy is converted to a less useful form we mean that entropy (a measure of the energy unavailable to do useful work) of the system has increased.
