cold-blooded
(ʊld)
Random House Webster's College Dictionary
of or designating animals, as fishes and reptiles, whose blood temperature ranges from the freezing point upward, in accordance with the temperature of the surrounding medium.
|
warm-blooded
Webster Dictionary
having warm blood; -- applied especially to those animals, as birds and mammals, which have warm blood, or, more properly, the power of maintaining a nearly uniform temperature whatever the temperature of the surrounding air. See Homoiothermal
|
heat
Webster Dictionary
high temperature, as distinguished from low temperature, or cold; as, the heat of summer and the cold of winter; heat of the skin or body in fever, etc

sense
Webster Dictionary
a faculty, possessed by animals, of perceiving external objects by means of impressions made upon certain organs (sensory or sense organs) of the body, or of perceiving changes in the condition of the body; as, the senses of sight, smell, hearing, taste, and touch.

entropy
Webster Dictionary
a certain property of a body, expressed as a measurable quantity, such that when there is no communication of heat the quantity remains constant, but when heat enters or leaves the body the quantity increases or diminishes. If a small amount, h, of heat enters the body when its temperature is t in the thermodynamic scale the entropy of the body is increased by h / t. The entropy is regarded as measured from some standard temperature and pressure. Sometimes called the thermodynamic function
