The change in energy of a system can be described by the equation H = TS + G
The change in energy of a system can be described by the equation H = TS + G. In organisms, H is equivalent to an organism’s total energy and is proportional to the organism’s dry mass.
Explain what S and G represent
Assume that the temperature and mass of an organism remain constant and the organism transfers energy from one molecule to another. Based on the 2nd law of thermodynamics, predict how you expect this effect to G and for the organism?
The total entropy and energy of adult organisms generally remains constant. Juvenile offspring actually increase energy and decrease in entropy. Considering the 2nd law of thermodynamics and your answer for part b, how can you explain this?
Solution Preview
THe S is the entropy that is the energy of disorder of molecules while G is the free energy which is the minimised energy of a reaction to reach equillibrium. According to the second law of thermodynamics ..
