1. This equation has been derived in the case of reversible changes . 2. These reversible changes could also explain why dysfunction is frequently temporary. 3. This form of treatment causes reversible changes and does not cause any permanent lesions. 4. Other studies suggest little change, or reversible changes after only the first few minutes. 5. Elastic deformation in solids is reversible change in the internal molecular structure of an object. 6. It effectuates leaf motion due to reversible changes in turgor pressure, which occurs without growth. 7. Kanazawa s group investigated the reversible changes of PNIPAAm once modifying it with a carboxyl end. 8. Since, and are thermodynamic functions of state, the above relation holds also for arbitrary non-reversible changes . 9. Since U, S and V are thermodynamic functions of state, the above relation holds also for non-reversible changes . 10. The room-temperature form of quartz, ?-quartz, undergoes a reversible change in crystal structure at 573 �C to form ?-quartz.
