Zoophilia is a paraphilia involving sexual activity between human and non-human animals or a fixation on such practice. The term zoophilia derives from the combination of two nouns in Greek: ζῷον ( zṓion, meaning "animal") and φιλία ( , meaning "(fraternal) love"). As a suffix, -philia indicates an abnormal liking for or tendency towards a given thing. Thus, the term denotes an abnormal human sexual attraction to animals.Princeton University, WordNet, " WordNet Search - 3.1 'Zoophilia'". Ac..

Thermodynamics is a branch of natural science concerned with heat and its relation to energy and work. It defines macroscopic variables (such as temperature, internal energy, entropy, and pressure) that characterize materials and radiation, and explains how they are related and by what laws they change with time. Thermodynamics describes the average behavior of very large numbers of microscopic constituents, and its laws can be derived from statistical mechanics.
