Document Summary
Can only be converted from one form to another. 3. 1 bioenergetics: the study of the various types of energy transformations that occur in living organisms. The laws of thermodynamics and the concept of entropy. Energy: the capacity to do work-capacity to change/ move things. Thermodynamics: the study of the changes in energy that accompany events in the universe. The first law of thermodynamics: the law of conservation of energy-energy can neither be created nor destroyed. The second law of thermodynamics: expresses the concept that events in the universe have direction-tend to proceed downhill-from a state of higher energy to a state of lower energy->> a decreasing availability of energy for doing additional work. Spontaneous: thermodynamically favorable and can occur without the input of external energy. Loss of energy during a process tendency for randomness or disorder to increase whenever there is a transfer of energy. Every event is accompanied by an increase in the entropy of the universe.
