1. This can be regarded as a cyclic process . 2. This is because in cyclic process the variation of a state function is zero. 3. Rather, it is the aggregate composition of species that gives rise to the cyclic process . 4. This is because in cyclic processes the variation of a state function is zero from state functionality. 5. Thus animals and plants obey the second law of thermodynamics, considered in terms of cyclic processes . 6. One possible explanation for this event is that it is part of a cyclic process on Venus. 7. A current goal is to obtain an NADPH-inspired catalyst capable of recreating the natural cyclic process . 8. For any cyclic process , there will be an upper portion of the cycle and a lower portion. 9. A cyclic process is one that can be repeated indefinitely often, returning the system to its initial state. 10. It is easily shown that the efficiency \ eta is maximum when the entire cyclic process is a reversible process.
